Resolution of Transparency

Hi
I would like to know how the resolution of a transparent object is determined when exporting to a 1.6 PDF where the transparency is not flattened. Does it use the settings in the transparency flattener Preset? Or is it related to the resolution of an image sitting below the transparency?
I have an indesign page that has a placed illustrator vector graphic that has a drop shadow in it. The drop shadow is causing problems when exported to a 1.6PDF because the resolution is too low and Im wondering how to control this.
Thanks in advance for your help!

Go to
Effect=>Document Raster Effects Settings.
Set the resolution there to either
High (300ppi) or
Other: and enter a higher number as appropriate.
Note that Illustrator 14 (CS4) pre-populates that resolution field based on the
New Document Profile you select when you are creating a new document and that in the
Advanced options for
New Document you can set the
Raster Effects Resolution directly there to the preset values of either 72ppi for
Screen, 150ppi for
Medium, or 300ppi for
High. (Custom values require using the
Effect=>Document Raster Effects Settings method.)

Resolution question - transparent PNG

Opened a 2MB transparent background PNG, made some small edits, saved back to transparent background png and now file size is 34MB. Didn't change the dimensions of the file or it's resolution. What is happening? I thought I was well past the stage of understanding how this all worked but apparently not.
Thanks
Ben

Hey sorry for the delayed reply I really appreciate your help on this. You know upon further review I think there were layers involved when I thought there were none. I went back and looked at things with fresh eyes and now my edited photo is only about 6MB (I had to increase the DPI though so that does make sense) But since I'm here maybe you can answer this : What is the difference between the 2MB file size when I "get info" on it, and the 51M size the dialogue box displays in photoshop? (the photos below are the same file obviously)

Problem in PDF after creating from Indesign CS3 (transparancy)

Hi all,
Please give me a solution ASAP, its most urgent.
We have used two color in one image, the color color is pantone.
First we have selected the one pantone in image and in background another color. After creating PS using Prinergy and Distilling.
I am not getting the result, the PDF which I have creating, the image contain only the main color not the background color, if I use the the "Advance - "Output Privew I am getting the result in PDF, what would be the problem, I have used "High Resolution" in Transparancy, still I am not getting the result.
Please respond ASAP.
Shaji

Are you colours defined as spots.? If you do not need spot colours in your job, then change them to process in the swatches panel.
Otherwise you will need to configure the RIP honour the overprints.

Save as EPS with High Resolution

Hi,
When I save the file as EPS , I want to enable all the options in EPS Options Pallet. I have enabled all options except setting high resolution in Transparency option. If anyone knows please help me.

Then, any other way to process this. How can I continue this process.

High resolution PDF still generates low resolution drop shadows?

I have created a series of print ads in InDesign CS5.5 to be run in magazines, and at the bottom of the page is the company's logo, with a drop shadow applied to it within InDesign. Nothing strange there. Upon exporting the PDF, I use the Press Quality settings which by default are made to create 300 dpi PDFs. The only changes I make in the settings is adding bleed and crop marks, I don't change anything that could affect the resolution or transparency settings. But still, the magazine's print-technician always replies that the shadows in my document have a low resolution.
Up until now I have told him to not worry and run it anyway, and the results have been fine - I haven't noticed any problems with the quality of the print in the magazine. But it really annoys me that I keep getting these error messages - I want to create perfect PDFs! Why on earth are my shadows ending up as low resolution images?
The only thing I can imagine might be a sign of an issue is under the Advanced-tab in my Export-settings. The Transparency Flattener section (which I, to be honest, am not quite sure what it is) is set to medium resolution, and is greyed out - meaning I can't change it to high resolution. Could this be what is causing it? And if so, how do I fix it?

I don't spend a lot of time with Acrobat's preflight, but it looks like it assumes what the flattener preset will be at output even though it could be anything.
The default Press Quality preset exports live transparency with the flattener grayed out as Medium and it looks like Acrobat preflight considers that even though nothing has been flattened yet. So, here I've made a 3" sqaure box and exported it with Press Quality and prefilght tells me it's roughly 200ppi (which by the way is plenty for a dropshadow):
If I change the preset to High (set the Compatibility to 1.3, which lets you set the flattener to High, then reset compatibility to 1.4):
Then Acrobat's preflight tells me the shadow will have more resolution:

What size should my background layer image be for web?

I'm doing a logo design for someone I know and he wants it placed ontop of a steel texture background. I've sourced out a good quality image but despite my diligence in trying to understand how image size and resolution works, I can't seem to grasp what I need to do with it. I've watched countless videos, but it must be a problem with the ol' brain in the head I have.
This is most likely (at least for now) just for web. My main focus is just getting this right so that it looks crisp and sharp on screen.
The image I have is 1024 x 1384 pixels 72dpi. So 14.2 inches wide by 19.2 inches high.
Do I need to change this at all? I will be cropping the image, but I'm worried that I will make it too small and therefore it will need to be enlarged and I might encounter some blurring.
Should I enlarge it? I heard this isn't the most ideal thing.
72dpi is as high as the resolution needs to be for screen images, but is there any advantage in bumping that up? Why couldn't I just make it 300dpi for the heck of it?
Do I need to pay attention to inches, or is that just good guide for when you are printing something?
I'm honestly just trying to get my head around it all so that in the future I don't have to spend so much time figuring out what I need to do. Everything I read and any help is greatly appreciated.

Ok be prepared for a dumb question...
If you're telling me to forget dpi/ppi when working with screens, how come you then say to think in terms of pixels for screens and to double the resolution for retina screens? I'm obviously a bit confused about the terminology here..
With screen based design work, design with pixels in mind. So if you design for a website that is 1140px in width, then that is your base target width. With retina screens the screen resolution is effectively doubled up, but the relative size of elements show on such a screen is ideally the same as if you would be working on a screen with half the resolution.
Example iPad:
old iPad: 1024x768px.
new iPad retina: twice that: 2048*1536.
Your logo would be rendered at the same size on both screens. Let's say at 800X400 on the older screen. Because the retina screen behaves like a 1024x768 screen in rendering all elements, but effectively doubles the available resolution, you would have to provide an ipad developer with a 1600x800 version, which can be used for both screens, and makes sure that it looks razor sharp on the retina screen.
No ppi. No dpi. Think in pixels only. With 4k screens around the corner this will become even more harrowing. That is why we are currently seeing the return of true vector graphics for screen and interface development. To complicate matters, since this is a relatively new development a lot of information on the web is completely outdated. I would not trust most info that is much older than two years, and double check even that. Check out Apple's icon and graphic creation guide for more ideas:
http://developer.apple.com/library/ios/documentation/userexperience/conceptual/mobilehig/I consImages/IconsImages.html
Now, things become even more confusing once you decide the graphics have to be prepared for a fluid and/or responsive designed web page or application. That background graphic you chose will not work well at all on a web page background, because it does not seamlessly repeat. That means it will be automatically scaled up and down to cover the entire browser window frame. Using an ultra-high resoluton background image just will not do: it eats up video memory for breakfast, is slow on certain devices, and may take ages to download. For these reasons, and many more, you need to be efficient and clever.
So I would choose a seamless repeating metal background with enough detail that does not stand out too much (otherwise it would be noticed too much as to repeat). Another trick is to provide a lower resolution alpha transparent png mask to add a soft lighting effect to the metal background, and perhaps the logo. That png mask could then be scaled up because you would not notice the low resolution at all - better, the mask would become fuzzier, which does not matter for a soft lighting mask! Even a 512x512 mask or lower would work very well.
That logo of yours (second image) will NOT render as a vector at all. It must be saved as a bitmap.
The logo in the last image could work as an SVG, and become completely scalable on a web page or in an application (depending on the support for SVGs)
Bottom line is that, for web page development and for app development, seperate layered versions will be required for the highest quality and most flexible result. A merged version will probably be quite useless. At least, it would be for me as a website/app developer and UX designer. Ideally I would like access to the Photoshop file, but I will settle for high resolution png files for each element. And if vector files can be send to me as SVG files: YES PLEASE!
So the question remains: what are the client's output requirements? Is this for a website? What are the target platforms? And so on. Also remember that most people probably would not notice the difference between a "normal" 1024x768 image and a retina version for a background like yours, because the focus would be on the logo. So another approach is to provide a lower resolution (smaller file sized!) background image, and a higher resolution logo image that takes advantage of retina resolutions. Our brains cannot differentiate a lot of detail in darks. Take advantage of this.
Hope this helps a bit!

I am writing a book to be published. how to i get my pages documents to PDF or JPG or something else that is at least 224 pixels per inch?

i am writing a book to be published. how do i get my "pages document" to a high definition level...at least 224 pixels per inch? i can get to 150 ppi via preview to JPG, but that seems to be the best i can do with my new snow leopard imac.

Hello Barbara,
> i have text written in Pages and these need to be at least 224 ppi.
i also have photo collages that were created in Pages and also need to be at least 224 ppi.
the book has about 60 pages of photo collages and about 30 pages of text.
If you want to print using a digital press or an offset lithographic press at high resolution, then you typography is resolution independent but your photography is not. In other words, you must embed into your Pages document the images in the resolution that is right for rendering in the high resolution raster image processor.
Raster image processors will as a rule of thumb produce good quality detail if you embed photographs with 300 dot per inch resolution. Because raster image processors differ in how they reproduce detail, and because this information is generally not public a rule of thumb principle is applied in preparing the page description for printing.
By default, if you use colour transparency in your work, the system graphics service will detect this and save out PDF 1.4 automatically. However, not all raster image processors have PDF frontends that accept PDF 1.4. For this reason, there is a fallback which you must set up yourself.
If the receiving raster image processor does not have a PDF frontend that accepts PDF 1.4, you have to manually enter the resolution at which the transparency will be rendered. The system graphics service will then render the resolution for you and save out what it technically termed a 'flattended PDF'.
Alternatively, if you don't want to work with the Apple ColorSync Utility yourself, you can send your PDF 1.4 with resolution independent transparency to a prepress operator who will then use specialised software to render the resolution for the specifics of the service he or she is selling you.
If you want to work with the prepress interface in system graphics services, then below is a link to summary on setting up the ColorSync Utility for ISO 15930-3:2002 PDF/X-3. This passes prepress preflight testing in Adobe Acrobat Professional 6.0.1 (the first version that tested for PDF/X-3).

Printing to pdf is blurry in Acrobat 9 Pro

I'm running Adobe Acrobat 9 Pro. When I print a PDF document using the Adobe PDF printer, the resulting PDF appear with blurry text and images. Why is this, and how do I create a clear PDF?

Dear user,
I would like you to first check your Print Quality parameter from 'Properties'->'Layout'->'Advanced'->'Graphic'->'Print Quality'. You must have more dpis to get better output. Also check the resolution of Transparency Flattener preset from 'Advanced'->'Output'->'Transparency Flattener'.
If possible, Can you please forward us the original and output PDF at [email protected]
Looking forward to resolve your issue.
Thanks

Transparent logo into KN?

Mac OS10.4.11. Keynote 3.0.2
Logo created in Freehand.
I want to place a two colour logo (Call it "A&B") into KN on a colored background without its white picture box surrounding it. JPEG, TIFF, PDF files don't seem to work.
A Freehand vector EPS logo file works for me. A Photoshop EPS does not... it has a white box. What's the difference?
I sent the logo files to my client to use in his Windows Powerpoint. His logo files all have white boxes. He says the FH EPS file came in as a blank. What can I send him so the logo is clean... like it had a clipping path around it, without an actual clipping path?
His comments are:
I can take the jpeg and convert it to a websafe transparent background GIF in Corel PhotoPaint, but since it is a jpeg, the resolution is not high enough to produce a truly clean looking image.
I have a couple of programs that can open eps files. Both show that the image is completely blank and also indicate that in the image properties. If you have image content and I don’t the problem may be our email system stripping the content as a perceived threat. You could try imbedding the file in a zip file or emailing it to my home email where the filtering won’t be anywhere near as aggressive.
My question: What file format will work?

I can tell you that the difference between your FreeHand EPS and your PhotoShop EPS is that one is a vector and one is a bitmap. Since vectors are defined by the lines that make them up, if a background is not defined, then the object doesn't have one. Bitmaps are defined by their dots and I can't remember if EPS supports transparency of those dots. If no (or if you don't define those areas as being transparent), then you'll have a background every time.
As mentioned something that looks GREAT on a Mac will not look so hot in PowerPoint for Windows because it doesn't have the very nicer rendering engine that Keynote has. The tips in the other post should help towards trying to find SOME form of middle ground, though. Another thing that might be worth trying is to export the vectors as SVG, convert them with SVG2KEY, Open the resulting file in Keynote and then save THAT as a PowerPoint file. If the shape gets transferred correctly (another big if) then your client will have a logo that can be resized to ANY size or even have it's color changed. This works best on logos or artwork with very few colors, that's why I offered it as a suggestion.

If you've got GraphicConverter, you can import your JPG, hit the background with the transparency wand, then save as either a GIF or PNG document to preserve the transparency. Of course, the initial resolution of the JPG will have some impact on the final result, but take a look and see if it's acceptable or not.

Camera resolution for NetStream. Please help.

I'm developing a videochat app that should work on different network speeds. The idea was to switch to lower resolution if by some criteria delay becomes too noticable (say, delay is 2 seconds, or dropped videoMessage packet ratio is more than 20%). Or if on the other hand user has fast network connection then app should increase the resolution and thus providing better video image quality.
The problem: I can not find anyone done this before, thus I am comming to the conclusions that I'm doing something wrong here.
Is it possible that RTMFP is lowering the video image quality automatically when ever it thinks that delay is too huge? If this is the case, than should I set the video resolution for camera to 1600x1200 and feed it to the netstream and allow NetStream to take care of everything else, or there is some other magic numbers for resolution that I should set?
If this is not the case and RTMFP is not taking care of lowering/increasing video quality automatically then how can I measure the quality. I know there are NetStream.info and NetStream.liveDelay, nether of which for RTMFP connections provides valuable information to detect delay. For me liveDelay is going up to 20 and then fluctuacting there, but for info videoLossRate property is always zero, even if I set everything to max and lag is very noticable.
So how is RTMFP intended to use?

I agree. In fact, make it your workflow when sending this type of file to an online vendor. The importance of the 350ppi requirement is for any of your transparency or raster effects to match their RIP's output line screen. It's becoming an industry wide mistake to refer to file resolution in terms of dpi. Do yourself a favor and get familiarized with the terms dpi and ppi, what they really are and what importance they play in output. The advantage to PDF is the fact that you can establish the output resolution, color settings, and font embedding that will trim the variables that could go wrong on the vendor's end. Your job is to make sure you apply the correct resolution, color, and font settings in the original file and again when you generate the final PDF. If you are unsure, find a local print provider that knows what they are doing and can teach you how to setup a file properly. You may have to intern somewhere, take a good course somewhere, and/or buy a really good and accurate book on prepress file standards. Try your local book store or library. Use better keywords when searching on the web, take a look at some of adobe.com's resources ( i.e., A Designer's Guide to PDF or similar ). Now, you will need to learn more about Illustrator Color Settings and the Raster Effects Resolution Settings. These are two areas you should spend a little time getting to know how different settings will affect output. In the case of your business card, set the raster resolution to "High". That will cover you on their 350ppi requirement. Do not get discouraged by seeing their proof on screen. It's just a preview. Do not get too comfortable with what you see on your screen unless your entire workstation is calibrated and even then you have to be cautious.

Low resolution Illustrator file needs to be changed to high resolution?

I created a logo for a client in Illustrator that they were going to use on large format banners. The file contained one Photoshop image that I imported into my Illustrator file and changed into a vector object. I also outlined all type. The only other items on the logo were colors done in CMYK. The client now says the overall image was done in 'low resolution' and needs to be in 'high resolution' but I'm confused about what part of the design she would be referring to (as, as far as I know) there are no pixels that would pertain to resolution - (unless the CMYK color builds translate into a problem?).
As she is a new designer for a client (my friend) I'd like to get some feedback before I just ask her what she's talking about and embarrasing her (or me).
Any thoughts? Thanks.

I'll note... after reviewing my file, the only other thing I noticed was under Document Setup, the Transparency preset was at 'Medium' instead of 'High' resolution, but here again, I thought this was a non-factor because as far as I know there is no 'transparency' (no jpegs, effects, etc.)... just the vector items that I noted.

Is there a way to change the color of the Bezier Curves and points to a different color other than black I find it perplexing while setting points and curves working on a photo that needs to be separated from it's background for placement on transparent

Is there a way to change the color of the Bezier Curves and points to a different color other than black I find it perplexing while setting points and curves working on a photo that needs to be separated from it's background for placement on transparent backgrounds. Any thoughts?

Yes. Well, sort of: instead of a "path", set the pen tool to "shape" in the tool properties. Then set the fill colour to transparent, and the stroke colour to the colour you want. You can also set the stroke width.
Not perfect, but at least you can see the path more clearly - the anchor points and handles still remain the default colour. Open the path panel, and right-mouse click the path shape to create a selection based on that shape. The Paths panel menu also allows you to create work paths based on that shape.
Unfortunately when you try to move the handles the black thin outline appears again until you release the mouse button.
This is one of several things that works better in Photoline: in Photoline, once the path is set to a specific colour, editing the path uses the actual colour and stroke width. which is extremely handy for creating path based selection with awkward background colours and/or a high resolution screen. In Photoline the handles and bezier points are also much, much larger, which makes it rather simpler to work with as well - especially on a higher resolution screen. And when selected the handles and points are a clear red with a black outline - again easier to spot and identify. I just works better, in my opinion.

ImageIO, Timers, Transparency and a Rant

Hi all,
<BEGIN RANT>
After years of writing games and programming next-gen consoles, I foolishly decided to write a few online java games. Like many, I chose Java because it is very similar to c++ and accessible cross-platform on web pages by the masses with no extra downloads required (btw, I'm not using j3d for this reason). Instead I've found it to be nothing but a burden.
Today's gripes are below. If I sound like I'm having a rant, well, adter fighting it all this week, I am!. Any help/suggestions/discussions are most appreciated. I'm currently using j2sdk 1.4.1_02.
1) why can't I enable hardware accleration (currently transparency sucks on the framerate) without requiring permissions? What exactly am I going to do with it to make it a security risk?
2) Why doesn't Java (without j3d or any other extensions) support the high-resolution timer? Such a basic issue that has been plaguing these forums for years. It seems i can't even do a work around as using JNI requires permissions and an external module on the users machine so I can't do this from an APPLET without signing and installing something. Sure, I could just about use 15ms on w2k and make win98 users suffer 20fps with the 50ms res timer. I tried (and succeeded) using my own timers but that means I can't sleep (as sleep>0 will sleep for at least the timer resolution) so my cpu usage is on 99%. And it destroyed my win98 machine :-)
3) Has anyone had problems with ImageIO.read in an applet? I find that occasionally when reading an image from my web server, it reads it twice (I guess it found an error and re-requests it) and corrupts the image. At first I thought it was my php corrupting the image, but it does it on direct accesses as well. Toolkit.createImage does not seem to have this problem (but then I have to wait for it to load (currently i construct a cursor with the image which seems to sort it) and then paste it to BufferedImage rather than the inaccessible image type returned by toolkit). Toolkit does however have the advantage that I can use extensionless image files and prevent caching though which ImageIO.read seems unable to handle (it usually loses the palette of gifs etc without the extension hint). My web server is apache 2.0.45 on Win2K btw.
These issues concern APPLETS. If i wanted to write an application, I would use C++ and OpenGL with very little extra work required for each specific platform (I'd only support PC, Mac and x86 based linux anyway). The point is that i want it embedded on a web page, and I don't want the user to have to install anything other than the Java VM.
What about the rest of you?
What are your experiences with Java? Good? Bad?
Do you guys think there is any future for it?
Does Java 1.5 have anything to offer?
IF it comes down to it, and I NEED to sign my code and INSTALL code then I will just abandon Java altogether and just stick to windoze users (It will take a fraction of the development time and be far less painful for me to use ActiveX or .net).
Oh, and if you're just going to reply and say something like "I think Java's the bestest thing ever, it's so much better and cooler than C++ and all my friends think so too. Cos my teacher says so" then don't waste my time.
If you have games experience and know what you're on about then I'd love to hear your views.
<END RANT>
Cheers

Hi Paul,
Thanks for your views.
Badly because it provides the security protections it
says it does?No, I mostly appreciate the security but some things seem a little too secure. For example, I want to use hardware acceleration for my translucencies but Java won't let me....
You can always ask users to change the permissions
your applet runs under, I guess, assuming the browser
support it. But at that point, why not just write
your game in C++ and tell people to download it and
run it normally?
If you're trying to write a Quake clone in java and
distribute it as an applet...don't bother.The point is that I don't want to do this. I want ppl to have to visit the web site to play the game without having to grant permissions or install anything or agree to run signed code (not just for advertising purposes but also as some of the games will be multiplayer). This is why I'm using Java and not activeX or .net.
I am perfectly capable of writing any genre of game to be cross platform in C++ (if I use OpenGL then I only need a thin platform-specific wrapper and I just compile it for my required targets - PC, Mac, x86 Linux), and I really don't see the point in attempting it as a Java application. The games I'm currently doing for my website in Java are simple 2d games suitable as applets. The main problem I'm having is that I need to sleep to free up the cpu, but the low-res timer resolution means that I can only run at 20fps on win98 when sleeping. Yes it runs ok, but by no means as smooth as I'd like.
I think java may be used in action gaming once it's
embedded into an environment that really supports it
(e.g., as a well-supported programming environment for
PlayStation 2) (and somehow I doubt that OpenGL
bindings for java will work as a gaming environment,
although that's just a hunch), and it's fine for
non-action games.Yes it can do the job, but the fact is that Java is and always will be slower than code compiled directly for the target CPU so this means my entire audience need to have higher spec machines to run it than I'd like. I would not write anything that is too CPU intensive in Java as there are also still a lot of low spec machines out there running win98 which I (unlike most ppl on these forums) am still willing to support.
Cheers
