Photo to PDF - Quality of PDF colour output

Hi!
Does anyone know of an photo to PDF app where you can alter the quality colour output of images converted? Like if you have an image of 2 MB for example, can you choose the output PDF-page to be of 0,5 MB, but still with colour?

The only method I am aware of to reduce the size of a photo and still retain color is to reduce the size (pixels) of the photo with a photo handling software. As in change a 1024x768 photo to 600x800. That will reduce the size. You can also change it to a jpeg, which will compress it, and then run it through whatever software you are using to convert to a pdf.

PDF Quality using PDF Print driver on Mac v FMP on PC

We’re having an issue that I hope you can help us resolve. When creating the same PDF document on a MAC v PC using Adobe PDF driver built into the Filemaker Pro we are getting a drastically different quality of document. Originally I assumed it was the original PDF driver installed on the PC itself since it was an off brand “LITE” version so I had the user remove all other PDF software and start from scratch with acrobat. Still getting the same results. I have no idea if and where quality settings would be found on the PC or in FMP to check those…
Any ideas?

Thanks for the quick response, Karl.
The client downloaded the trial version of Pro X, to verify that the form works before buying. Would the trial version impose restrictions?
The client does not want to store data on a server. He wants the form to function as a template that he can save-as to customize. The completed forms will be shown on the computer as a part of a presentation, sometimes without Internet access.
I tried using the Advanced > Extend Form Features options to enable to ability to save form data, but when I tested the PDF on my PC (Vista, latest version of Reader) I got an error message along the lines of "this document has been modified from previous version, please get a copy of the original" and all form fields are gone.
I'm currently downloading the trial of Pro X so I can test the PDF.
I am also using a Javascript to allow the client to place photos in the document. This is achieved using a button with a Javascript attached to it: event.target.buttonImportIcon();
This works correctly in my environment, but could it be screwing up the file as it's opened on a PC?

Quality of pdfs and colour separations for printing purposes

Having created a 44 page document in Pages, I have exported it as a pdf file so that it can be commercially printed as an A5 magazine. I have used the 'best' option in exporting it as a pdf, but have no idea if that function conforms to PDF-X1A specifications. Is there any documentation that would define the pdf standards within Pages?
The magazine is going to be two colour (headers/footers/callouts etc to be blue). So would the Print: ColorSync (then save as a pdf) option solve the problem that one printer noted:
"I have looked at the pdf you have sent and all seems ok with the quality but the colours don't split to the two separations (i.e blue and black) only CMYK (which is for 4 colour printing). If this does become a print job then we might have to look and see if we can get the pdf's to be the correct colour split."
And would this also ensure that the black is a true black and not a CMYK mixture that might not print correctly in the end?

Yes, this possibly could be a solution, but I did not want to have to buy another piece of software (ie Adobe Acrobat) to produce the newsletter. I like the control that I have over the magazine layout in Pages, but need to be able to ensure that the pdf file I create is of the appropriate quality. Exporting to 'Best' is probably okay, but as I am viewing the pdf using Preview I have little idea how the pdf will look to others. I have read posts that have had problems with the quality of the pdfs exported from Pages when opened with a Windows machine or using Acrobat, so I am trying to ensure that I don't experience similar problems.

Can anyone tell me how to convert crop marks to registration on a supplied pdf. The pdf also has spot colours which the crop marks need to be in too.

Greetings,
I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
Good Luck - Cheers,

PDF quality issues on Adobe Reader for Pocket PC 2.0

The quality of PDF's rendered by Adobe Reader 2.0 PPC is awful when compared to Adobe Reader LE. We are running it on HTC X7500's with a nice 5" display, but you have to zoom in +5x to read the text on our parts manuals, where as LE renders the same manual crisply and sharply and you don't have to zoom in at all to read the text. Unfortunately we use a lot of hyperlinks, forms and annotations in our documents which are only available with AR2.0PPC and not LE or indeed any of the other 3rd party readers (FoxitReader, PocketXPDF or Clearvue).
I'm assuming that this is down to anti-aliasing methods used, and that AR2.0PPC has not been updated for four years!
Are we likely to see a version of Adobe Reader for Pocket PC with the quality of LE? or have Adobe given up on developing this platform?

>>> Our techs have been using the HTC Blueangel (Same as the I-Mate pictured on your site), and although the image rendered by Adobe Reader was quite sharp, the size of the screen meant you were continually zooming in and out of pages to find the appropriate parts. So weve chosen the HTC X7500 as a replacement because of its 5 screen (amongst other reasons). <<
Ho Kay... have looked at the file and, based on the general layout (drawings with part# references) don't think you can get there from here.
Back to the basic goal, a couple of thoughts based on the assumption that your company is generating these pdf's and needs pda access to them.
Perhaps the part# references can be hyperlinked so the tech could tap the part# on the image and go to a table entry with all of the info on that specific part.
In that case, html would be a better format for navigation since, afaik, there does not seem to be a <back> button in reader.

PDF quality problems exporting from InDesign and Photoshop

Hi There.
I'm having big problems exporting my InDesign files to PDFs and retaining the res. And it's not just the images (I understand about the dpi) it's the type on there too.
I have been exporting as the preset High Quality Print - is this wrong. Are there other settings to ensure the PDF I export retains the high-res quality and clarity?
At the moment it comes out high-res when I export it as a jpeg or eps but not PDF.
I have also noticed the same problem when I export to a PDF from Photoshop.
I really need to create interactive and high quality print PDFs from my InDesign files.
Please can you advise.
Thanks
Karen

I am also having problems with pdfs exported from Illustrator and Indesign recently. I didn't have these problems before, so I don't kno if something has changed in my settings that I am unaware of.
When I use the 'japanese dots' border in Indesign, it shows on the pdf as a kind of dotted line. I'm exporting as 'High Quality Print'. I switched to Illustrator and drew a line with the pen tool, and converted it to a dotted line; it looked just how I wanted in in Illustrator, but as soon as I exported it, the same thing happened.
I have used the 'japanese dots' border in the past, exporting as 'High Quality Print', and not had this problem.
Does anyone have any suggestions?

How do I set the quality of a "save to pdf" or "mail pdf" ?

I have created a document (say, in Pages, MS Word, or Apple Works/Claris Works [yes, that is still an excellent programme..., even on an intel Mac] and then want to save it as pdf or " mail pdf".
If the document page has many pictures, the pdf created via the "Print" function in OS X has quite some pixelation and the print-out is sub-optimal (eg for a Christmas/New Year card).
Is there a way that the quality of the created pdf file can be altered?
Any advice would be appreciated.

Audition's native recording and processing format is 32 bit floating. This allows for the most accurate processing of your audio. You cannot set it to record at 24 bit depth. However a 24 bit source is happily stored in the 32 bit format when you record from an external 24 bit audio interface.
If you need to save 24 bit files for use after you have finished editing them then you choose 24 bit from the Options drop down in the Save As panel when you save the file.
See further explanation 24-bit hardware with "32-bit float" recording in 3.0

Book Module Export PDF Quality Poor - any solutions?

Hello,
I am trying to figure out a solid solution / workflow for making PDF porfolio's for clients.
The commercial studio where I work needs to send pdf portfolio's to potential clients quite often.
So far we have not been able to find a perfect solution on how to do this with any adobe product (including ACROBAT!)
one of 2 things seem to continually happen.
1. Gigantic file sizes for decent quality PDF's (75 mb +)
2. Horrible color shifts and degraded picture quality for usably sized (3-7mb) portfolio's.
I was hopeful that the new Book Module in LR4 would solve this issue.
admitedly the quality is better IF I save it at jpeg quality 100 and a dpi of 240 but this resulted in a 74 MB file (for 31 images on a 8x10 page)
I clearly can not send a file that large with email....
as soon as I make the dpi or jpeg quality lower they look like total garbage...
Further more the colors shift greatly (on the lower res versions) when opened in something other then Acrobat reader (ie Mac Preview)
Could someone please share a workflow that will result in profesional quality PDF's at a screen resolution.
We have / use the CS5 suite / LR4 / Acrobat Pro
In short as a PRO studio I want PRO quality our of my PRO software...
I would like to keep it as simple and streamlined as possible.
and if at all possible do it all within LR4.
Any help would be greatly appreciated.
thanks.

Thanks, I haven't used the LR4 Book module that much and only saw the 'Export Book to PDF' button at the left-bottom of the screen. I tried a Book module 'PDF' Export using 7x7 size, Quality 80, sRGB, 150 dpi, and Standard Glossy sharpening. Here are the results:
1) PDF file size = 3.3 MB
2) Standard Optimized PDF (Acrobat 9 compatibility) = 3.2 MB
I next tried the 'Export Book to PDF' button:
3) PDF file size = 4.8 MB
4) Standard Optimized PDF (Acrobat 9 compatibility) = 975 KB
When viewed on my 25" 1920 x1080 monitor on Windows 7 64bit in Acrobat 9 Pro at 'Fit to Page' zoom size all four PDF files look identical in color and sharpness. When viewed in 'Full Screen' mode only the largest file size PDF (#3 above) created using the 'Export Book to PDF' button exhibits good sharpness. This is probably due to the size of the exported JPEG image having insufficient resolution to fill the screen at 100% (1:1 pixel mapping):
7" x 7" Book at 150 dpi = 6.88" x 150 = 1032x 1032 (Mapped to my 1920 x 1080 monitor)
Requires 1080/6.88" = 157 dpi minimum
7" x 7" Book at 170dpi = 6.88” x 170= 1170 x 1170 (Mapped to your 2560 x 1440 monitor)
Requires 1440/6.88" = 210 dpi minimum
I next created a Book PDF file (3.7 MB) with the above calculated 157 dpi for my 1920 x1080 monitor viewing in Full Screen mode. The results are as sharp as the full-size ‘Export Book to PDF’ file (4.8 MB). I then tried a PDF optimization of the 4.8 MB file using Acrobat Optimization downsample setting of 157 dpi for images above 235 dpi and obtained an equally sharp file 1.0 MB in size. So this method still seems to produce a smaller file than obtainable direct from the LR Book module.
For your NEC MultiSync PA271w monitor with higher 2560 x1440 resolution try using 210 dpi, 80 quality and Standard Glossy Sharpening. When I used Matte High settings the image was clearly over-sharpened for screen viewing. Next try the ‘Export to PDF’ button and then ‘PDF Optimization’ in Acrobat Pro using 210 dpi downsample setting. It shouldn’t hurt to go slightly higher in dpi, but you don’t want to go lower than ‘Full Screen’ 1:1 pixel mapping.

Setting default export quality for PDFs in Pages 5.0

Hi,
Anyone know if it is possible to set a default export quality for PDFs in Pages 5.0. Even if it remembered the last used setting that would be helpful.
Thanks,
Nick

OK, I have managed to get higher quality images from the PDF renderer. Here is what I have found:
1) The PDF renderer in Reporting Services 2005 will size all images that it is given at 96 DPI no matter what DPI the image is when you pass it to the renderer. That means that a 300 DPI image or even a 600 DPI image will be sized in the PDF as if it is only 96 DPI. That means your high DPI image will render much larger than you expect.
So you might expect a 300 DPI image that is 6.5 inches wide to render properly at 1950 pixels. Yet, the PDF renderer will size it as it were 96 DPI which would make the image 20.3 inches long!
2) There is good news though. Despite sizing the images as if they were 96 DPI, the PDF renderer appears to render higher DPI images at a higher quality than 96 DPI. So despite the sizing being wrong, the image actually is rendering at a higher quality.
This means that you should size the image to the proper number of inches based on 96 DPI calculations. Then you can use Bitmap.SetResolution to set your images to at least 300 DPI. That should give you a higher quality image that is the proper number of pixels to fit properly in your report.
I am able to do all of this sizing dynamically because I am using objects as my data sources, but I am sure there are VB functions you could use in the report itself to accomplish the same task.
It is late, and I've been at this project all day long, so forgive me if I have explained anything poorly or gotten any concepts long. Yet, at this late hour, I believe this is what the renderer is doing.
I hope this helps someone else in the future, or at least points them in the right direction.

PDF quality is degraded when InDesign file is reopened.

When I place PDF files in my InDesign document and print, or save to PDF immediately, the quality is great.
However, if I save the InDesign file and open it later, the PDF quality is much degraded. Too degraded to use.
I must make the document or book all over again.
Why does the PDF quality degrade when re-opening the InDesign?
HOW CAN I PREVENT THIS?
Thanks.

Regarding Peter's "be sure the link is up to date" because I was typing this after he posted:
Try placing a PDF into an ID doc, save the InDesign file, then reopen it. Select your placed file with the black selection tool, then go Window and select the Links panel. Looking at your linked image will tell you if InDesign can no longer find the image in the original location. (There'd be a yellow triangle with an exclamation point to indicate that the link is missing.) When you place your PDF into InDesign, a 72ppi preview of your linked file is saved in the INDD. In order to print, or export a good quality PDF, InDesign needs to be able to find the linked file.
So when you reopen, ID for some reason can't find the file. This could be caused by a wide variety of issues, but the most likely is that you moved either the InDesign file, or the linked PDF. Or perhaps your linked PDF is on an unavailable network drive? If you tell us more about your working environment, we might be able to figure out why the link is breaking.

Illustrator cs6: pdf export with hks colours creates b/w pdf...

hello forum,
i have a illu cs6 document with 2 hks colours and black. with »save as...« i want to create a printable pdf. but this pdf only has black-and-white, no hks, no colours.
then i changed the hks to cmyk. now the export as pdf works with the cmyk colours.
help, please, whats wrong?
thanks :-)

Try using the PDF/x-4 preset. If an all CMYK PDF is required, set the Color Conversion to Convert to Destination, and the Destination to Document CMYK.

PDF quality for print

Can someone explain to me if saving a file from photoshop or illustrator to PDF and sending it to press will lower the printing quality. Should I use native file format and avoid saving artwork to PDF, or it does not matter?
Thanks

The retention of your original quality depends on what settings you use. There are presets you can use in all the Adobe Apps you mentioned. For print use the presets
High Quality Print
PDF-X 1A
Both will not compress your images or changes colors. PDF-X is commonly requested by online print services.
"Smallest file size" preset will make your images RGB and compress them, this is good for emailing proofs for design approval.
As to whether to send print ready PDFs or submit .ai files along with fonts & images, depends on you and the print service you are going to use. If you have full confidence in the print service then send .ai files as your printer can make necessary edits (DMAX adjustment, thicken or thin up lines) . If you are sending to print in China for example, there are communications and quality/software version issues that can drive you nuts so you may want to just send them print readyPDFs.

Creating SAME SIZED pdf from two pdf's

i am probably not following instructions very well and i am not finding an explanation in the documentation so i am hoping someone can help me out here.
i have two pdf's. one is a cover page of a magazine and the other is a page inside the magazine where my work is mentioned. i wish to combine these two pdfs into a SINGLE pdf but in a way that both the pdf's are the same size. i feel like i am missing a settings somewhere for this as each time i do this the inside page is printed into the pdf document at half the size of the cover page.
i have tried saving out as png and making sure they are the same size and resolution but this prints (out of Preview) with white borders all around.
i have tried saving out as Optimized pdf and setting the sizes to 8 x 11 and 72 dpi but this then prints out of Acrobat as a highly rasterized document that is unreadable.
can anyone help me with a step by step on how this can be done? it seems like i should just be able to open two random pdf's in the CREATE pulldown and then tell Acrobat to print them at some specified size (this would be very easy!) but i must be missing something.
TIA

Hotwheels 222,
It might help to think of PDF as a container that can have many things such as text, photos, graphics, vector elements,etc all wrapped up inside it.
Normally the content is created in another application such as InDesign, Illustrator, MS Word, or many other appliations. In the application you create a blank document and add or place images, type text in any font you desire, place or create some vector elements (if the application actually have any vector tools), and even other multimedia like audio/video as long as the application supports them,
The photos can all have a different resolution, the vector elements have no resolution (I'll explain), the text may be in many different fonts and they all retain their separate characteristics inside the PDF.
A PDF created from an application like Photoshop will just have one resolution because PS is a pixel based image editor and a PS document can only have a single resolution.
. . .the idea that two adobe products cannot communicate from acrobat to photoshop in terms of a pdf resolution in photoshop seems very inconvenient. . . Again, since a PDF may have many photos with different resolutions, even if PS could get this info (which it can't) what resolution should PS decide to use? PS leaves this up to the user to decide based on what they want their final output may be.
You mention a document you have that "appears to be no images inserted" and "it appears as if it is one image"?
Are you referring to the Cover pdf? The PDF producer is "Adobe Acrobat 10.0 Image Conversion Plug-In" is a tip off to "Test Screen Name" and myself that it came from Photoshop.
While its possible this document was completly created in Photoshop, it is also likely that it was created in another application like InDesign, etc. exported from there as a PDF and then the PDF was opened in Photoshop which rasterized the content and flattened it into a image file with the resolution that you chose when opening in PS and then saved again as just an image in the PDF format. The graphic artist that created this probably did this because they didn't want to give you a print quality PDF that you might try to extract elements from.
You mentioned you thought the doc was from Adobe Illustrator (AI) AI is primarily a vector creation tool which also allow for the inclusion pixel based raster images (with a specific pixel resolution) to be placed in an AI document if wanted. Strictly speaking, vector objects don't have a resolution. They are based on math,
It basically says, place a point at such & such X, Y coordinates, now place another poing at some other X,Y coordinates, it takes into account the arc or angle between the two points and says draw a straight line, or draw a curved line ,etc. Since these are only mathematical instructions. this can be enlarged as big as you want and the relationship between the 2 points and the arc of the curve or line will dictate how the enlarged line or curve will be redrawn.
Vectors are "resolution independent" you can draw a vector logo at 1 x1 inch, and enlarge it to 50 x 50 inches or even as large as a house and it will still print crisp and clean. Note, this only applies to the vector content in your document; any pixel content is stuck at the resolution it was created at.
To inspect elements in a PDF use the Object Inspector in Acrobat Pro. Since a PDF may contain many differing objects you need to click exactly on each object to get any info about the selected object. So if you had 10 photos in your PDF you would need to select each in turn and it would give you the pixel dimension, resolution, color space and profile, etc. if you clicked on text it will identify the font. It is well named, an Object Inspector rather than a Document inspector. Try it yourself with different PDFs you may encounter. If for example, it gives you the exact same info (resolution, pixel dimensions. etc) no matter when you click, then you are likely dealing with a whole single image. If you get different pixel dimension, resolutions when you click in various different areas you are dealing with a PDF that had separate distinct elements.
. . . i can't see why i shouldn't be able to get a document that is 17.7 x 22.9 at 72 ppi down to one that is 8 x 11 at 300 ppi.
In Photoshop, go to the Image menu, Image Size. This will show the pixel dimensions (width & height) at the top. If you don't interpolate (Resample) Photoshop can only put the same number of pixels into different size documents. When you squeeze the same # of pixels into a smaller doc the resolution goes up. When you place the same # of pixels in a larger doc the resolution goes down.
Remember, that resolution is PPI (Pixels Per Inch)! If you do the math this will start to make sense.
Below note that each dialog box has the EXACT same pixel dimensions.
In the first box it shows the 1275 x 1650 pixels in a document of 17.708 x 22.917 inches. This yields a resolution of 72 PPI.
In the second box I changed the document size to 8.5 x 11 inches and the same 1275 x 1650 pixels now increase the resolution to 150 PPI.
In the third box I changed the resolution to 300 PPI and the same 1275 x 1650 pixels now decrease the document size to 4.25 x 5.5 inches.
If you click the Resample Image box, Photoshop will interpolate (resample) the image by throwing away pixels or by adding pixels, but there is no magic involved, and the results are never as good as one might hope for.
Like Goldilocks and the 3 Bears, some things are best when they are "just right"

Text issues merging multiple pdfs into one pdf

Hello, when I merge multiple pdfs into one pdf document my text is missing or garbled. I spent hours yesterday trying to figure this out, from insuring the text was embedded and print setting were correct. Please help!!
Using Adobe Pro 9.0
Thanks,
Faith

Acrobat Pro is the application you use for working with PDFs, making minor edits, combining multiple PDFs into a single file, extracting or replacing pages, doing fancier form work than ID has the ability to produce, and even creating PDF from a number of other file formats. I'm not sure your question about maintaining the quality of your photos is really applicable -- it would depend on how youare getting from the photo to PDF to begin with. The use of Acrobat in and of itself won't be the determiner.
That said, I couldn't live without Acrobat Pro in my workflow. Since you are on CS5.5 you have a couple of options. You could purchase a subscription to Creative Cloud (at a discount for the first year), which would give you access not only to Acrobat, but all of the other programs and tools included in the suite, but you pay a monthly or yearly fee, or you can buy a standalone perpetual license to either Acrobat Pro or Acrobat Standard (I didn't realize Standard was still an option, and you might not need all the features of Pro -- you can compare at http://www.adobe.com/products/acrobatpro/buying-guide.html).
