ID5.5 image dpi cut from 300 to 150 in save as ps, acrobat to pdf

When I submitted book interior to printer, they said some images were 150 dpi. I checked the ID file links, and they showed them as 300 dpi. My process to pdf was: from ID, save as postscript file, then use Acrobat Pro with the PDFx1a2001 profile to create the pdf. Any thoughts on where in this process the images would be downgraded to 150 dpi? Here is the file as ID shows it:
Thanks for any suggestions.

Not really.

Iphoto converting edited photos from 300 dpi to 72 dpi

I edit RAW photos and save as Jpeg The dpi reduces from 300 dpi to 72. I have seen an archived discussion saying basically this does not matter. The size of my photo is 3872x2592 for 2.4mb when edited. Unfortunately a newspaper has refused to print a photo as they will only print at 300 dpi. I have converted this photo back to 300 dpi using preview but apparently 'blowing up the pixels blurs them? Is there any way I can edit and still maintain 300 dpi?

Yes you can do tat but it akes NO DIFFERENCE - the newspapr has no idea how digital photography works
see http://www.rideau-info.com/photos/mythdpi.html for more details
Simply put no digital file has any DPI (yes there is a DPI field in the EXIF data but it is simply a number and any competent printer simply ignores is since it is meaningless
DPI is dots per inch and therefore can not exist until you have "Inches" - until you print - then DPI is a simple mathmatical calbulation - the dots (pixels) divided by inches (Dots Per Inch)
If you give the newspaper a 3872x2592 file then they can print it up to 12.9066667 Inches x 8.64 inches at 300 DPI (3872/300 x 2592/300) -- if the print is suppose to be larger than that then you need a higher resolution camera
And although it makes no difference newspapers do not need more than about 120 DPI because of the overall quality of their printing

Bridge Exports Changes Resolution from 300 to 72 dpi, resizing my image

I like to use Bridge (CS5) to export my photographs for printing, and frequently I will use the Export feature to resize the images (e.g., 5x7 vs full size), but every time I export it recharacterizes the images as 72 dpi, vs the 300 dpi I prefer.
Consistent with some of the previous postings (~2 yrs ago) I have seen on this topic the exported images are now "sized" much bigger (29"x20" for what should have been ~5"x7"), and hence expectantly I haven't lost any resolution, but it's aggrevating to have the dpi changed.
Can anyone tell me how to export without having the dpi changed?
And while I'm at it, can anyone confirm that I'm not loosing image resolution?
Thanks so much!!

Can anyone tell me how to export without having the dpi changed?
Can't find any other settings to change and just having tested it I can confirm that it sets ppi (it is pixels per inch -ppi- for a digital file which is made from pixels and dots per inch -dpi- from the ink dots of a print ) to 72.
And while I'm at it, can anyone confirm that I'm not loosing image resolution?
You already stated yourself that you did not loose pixels, therefor the size of the files stays the same. It is just a mater of figures. 300 ppi means a larger concentration per inch and 72 pixels per inch means a smaller concentration of pixels per inch. Given the same amount of pixels for both settings this means a smaller image dimension for 300 ppi and a larger image dimension for the 72 ppi.
300 ppi is some 'magic' number from printed press, but it really depends on the need of the job related printing machine. If you have a small image and need to look closely it should have a larger concentration per inch to reflect its sharpness.
However theoretically you would almost have the same visible quality when printed on 72 at billboard sizes. That's because you always have a large distance between your eyes and the bill board. If you look closely you will see the dots (because the billboard is a product of ink dots…) but of course it is not meant to study at that close range.
The same is for judging sharpness on your computer. Ideally you do so at 100 % for correct judgement at real size pixels. But in reality there will be almost no situation you will study a print at that same distance
Any thoughts on why these would be different? And am I fretting over things unncessarily?
Only guesses, the use a different algorithm or calculation scheme, in my case I tried a Canon Raw (converted to DNG) without any ACR settings then the basics applied and found that Bridge export jpeg 11 creates larger files then using PS.
But there are some other concerns I have and that certainly would make me fretting in use of export module:
First of all I almost never use it, merely in this cases for testing, because using the menu tools give a shortcut to Photoshop / Batch and inhere I have created several dedicated resizing and resaving actions that also places the files in preset folders.
But with this small test I found out that
a: it changes ppi to 72 ppi, not a very big deal but I did not asked for it nor did I wanted it.
b: it converts my Adobe RGB color space to sRGB and I certainly did not want that without my explicit wish for this conversion, so this is more then a bit worrying to my concern.
c: it seems to apply a sharpness that I certainly did not want to happen without my knowledge, and this rules the use of the export module out completely.
Since I only tried a DNG file without settings or retouch/developing in Photoshop the jpeg generated by PS was not very sharp. This makes sense to me because I have set my basic ACR to apply sharpening only to preview. There are a lot of different sharpening theories around but I use one in PS itself. So I was a bit shocked to learn that the export module did all those for me unwanted and not adjustable settings putting me completely out of control…
So if you want to have full control about things happening under the hood yourself just start creating actions in PS, it is very easy to record an action and even more easier to play it. Instead of every time dragging files to export module and always recheck the image options (it seems to reset itself always to jpeg quality 8 on my system) only select the files you want to resize and choose menu tool / Photoshop Batch and select the wanted action. hit OK and your almost done, PS does the rest.
The great thing of the latest PS CS6 action pallet is the extension with a so called 'insert conditional' that let's you create an 'if - then else' action for both landscape and portrait resizing actions so you don't need the 'constrain to fit' or 'fit image' option. Just once create an action for both resizing dimensions and then create a new action with insert conditional. choose If image is landscape play action…. / else play action….
It is really a very productive way. I have a lot of actions (organized in sets for better overview) and even one that creates 4 different sizes in 4 different folders using 1 go in Bridge

Sending hi res (300 dpi) jpegs from Lightroom 4

I am taking a course on making Christmas decorations. Have been asked to send my images @ 3" x 3", 300 dpi, medium jpeg. We have spent 2 days back and forth with this and I have not been able to complete the Export panel correctly. Can anyone help. Thanks.

I had cropped my image to 3 x 3 first.
Unless you want square pictures, crop to whatever dimensions are most pleasing, e.g. 4000x3000 (i.e. as big as possible preserving the portion of image you want), cropped dimension bears no relationship to print resolution (which is what the dpi value is referring to, or should be).
If you truly want square pictures, then crop to 4000x4000 or 3000x3000 or 2000x2000 etc. in other words: crop determines aspect ratio (overall retangular shape: square, wide, tall, ...).
Now that you've got them cropped correctly (or maybe they didn't need to be cropped at all - do you really want exactly square pictures?), you need to export them how she wants them, which, assuming she's using the correct terminology (or should I say terminology consistent with Lightroom's export dialog box), then export them at 900 pixels per side, max, and set (print) resolution to 300 pixels per inch.
That should do it.
If that doesn't do it, then you need to get more specific instructions from her.
Example settings:
Note: (print) Resolution merely sets a metadata item in the file, it (otherwise) has no effect whatsoever on exported image.
WallStShari wrote:
She said it only came to her at 240 pixels square.
An image exported with the above settings will come to her at 900 pixels on a side (square if cropped square, or rectangular with 900 pixels on long edge, if not cropped square). Just make sure you've not cropped it down to fewer pixels than 900 on a side, or you'll be losing quality, since it'll have to be enlarged to meet requirements. Greater than 900 pixels per side is OK, since Lr can shrink files without such quality loss.
Regarding Jpeg quality: 90 is very high, 80 is high, 60-70 is medium, 50 or below is (relatively) "low" - roughly and subject to opinion.

How stop PS6 from removing the DPI value from an image when using "save for the web"?

How stop PS6 from removing the DPI-value from an image when using "save for the web"?
Example:
- Open a tif image, that contains a dpi value (resolution).
- Use the splice tool in PS6.
- Export the slices with "Save for web", as gif-files.
Then the dpi value is removed, the gif files has no dpi value (it's empty).
How can we stop PS6 from removing the dpi value when using "save for web"?
OR:
When using the slice tool, how can we save the sliced pieces without PS removing the dpi value?

you can make your art go a little bit over the bounds. or you can make sure your artboart and art edges align to pixels

Images cut from Microsoft Word document being picked up in the file size by Acrobat distiller

Hello All;
I have a large MS Word document (book manuscript) with almost 400 images (all grayscale) and found that the tiff images needed to be replaced with jpegs to reduce the file size. I created the jpegs, cut the tiff images from the document, and inserted the replacement jpeg image for each tiff image cut. It reduce the file size in Word from 595 Mb to 210Mb. However, when I ran the distiller, it is somehow picking up the file sizes of the tiff files as it still gives roughly the same output (595 Mb) for the Acrobat document. Is there a way I strip out the tiff image overhead from the pdf or a way I can cleanse it from the MS Word document? Thanks in advance.

Acrobat automatically compresses images when a PDF is made, usually doing something equivalent to JPEG (it's your choice, check the creation options).
So, changing from TIFF to JPEG in the original file will usually make not a bit of difference to the original file size.
There is no simple 1 to 1 connection between the size of a Word document and a PDF. Some things are bigger, some are smaller.
You can experiment with Save as ... optimized PDF settings. Also, use Audit Space Usage in that dialog to see what is using the space.

HOW TO SET IMAGE DPI

I read images which are 300 DPI . I get it in BufferedReader, and do some pixel manipulation. When I save those pics as PNG or JPEG the image DPI becomes 72 DPI. There should be a way to set image DPI when converting from Bufferedeader to .pgn or .jpg file.

I need to know how to set DPI to 400 without destroying the image data or pixel height and width. I know of two places within the header of a jpeg that this can be set a third I can see through debug information in metadata but cannot set. Why is this so difficult to manipulate?

InDesign Settings When Placing Image Screen Cap from SnagIt

I've already tried obtaining assistance from the SnagIt people, but they feel it's an InDesign setting I'm missing, which is likely since my skill with InDesign is very beginner level. Thank you kindly for any assistance.
I produce training materials for software and need to take screen captures that will then be inserted into InDesign. I do the production myself and then give to a printer.
I cannot, for the life of me, get the images to look half decent in InDesign. I save at 96 dpi, 300 dpi, tif RGB, tif CMYK, PNG etc. and to be honest, the captures look worse once they hit InDesign than if I took a basic windows screen cap.
The screen caps should be presented at a reasonable, readable size in InDesign as they are for instruction purposes. Professionally printed computer manuals is the quality I'm looking for.
SPECS:
CPU: Intel Core 2 Series Processor (2400 MHz) -- THIS IS A QUAD CORE
Memory: 4095 MB
OS Version: Microsoft Windows 7 64-bit (Build 7600) -- ULTIMATE VERSION
Graphics Card Vendor: NVIDIA Corporation
Graphics Card: GeForce 8800 GTX/PCI/SSE2 -- 2 SLI'd
Windows Graphics Driver Version: 8.17.0011.9562
I know I'm doing something wrong. The saved images look fine on my screen (I use ACDSee to view). But the moment I put them in InDesign, they look horrid (blurry, jaggy).
If you can't help me, do you know of someone who can?
I tried on the SnagIt forums, and no helpful responses.
Thank you kindly.
Sincerely,
Alexandria

You don’t say what’s wrong with the screen captures, but since you list several different resolutions I can guess. You are resampling and Photoshop is trying to produce smooth results, assuming the image is a photograph and that aliased (pixelated) details are undesirable.
Screen captures look best when they are not resampled. Save them in a lossless format like PNG or TIF and place them unmodified. If you edit them and add any layers or text (Layers panel shows anything but a single Background layer), then save as PSD or Photoshop PDF. Some print shops might either flag those low-res files as problems, or try to “help” you by upsampling them. You can avoid these issues by resampling in Photoshop using Nearest Neighbor interpolation. Use full 100% increments, ie: not from 72 ppi to 300 ppi (416.67%) but 72 to 288 ppi (400%).
Other tricks to explore are changing the antialiasing method of your display. Sub-pixel antialiasing is often used for LCD displays, but when enlarged and printed (look at the noise around “Font Family”) can be ugly. On a Mac you can turn this off in the Appearance Preference Pane.
Black can be a nuisance with screen captures. Your screen captures are probably saved in RGB. When they are printed the RGB values are converted to CMYK by the print shop. Normally, this is not something to be concerned with. But Black in RGB (0,0,0) is usually treated as a rich black or photographic black, and is converted to a colour with lots of each CMYK ink in it. For the fine type, dialogues, and lines of a screen grab, that is undesireable.
I have my own way of dealing with this, and I know others who have similar, but not identical, workflows. All require Photoshop. If you want further help with this, please ask either here or in the Photoshop forum.

How to change Tiff image DPI

I am looking for a code example to change Tiff Image DPI from 200 to 300.
Any suggestion is greatly appreciated.

You need to look for algorithms on scaling images. On such example is here:

Changing image dpi

I have several hundred images at various dpi and I'd like to convert them all to 300 dpi. I can change the resolution manually with Preview or Photoshop CS5 and it's also easy to change all the image sizes with Automator, but I can't figure out how to automate a dpi conversion. Anyone have any suggestions?

Obviously the value is stored within the file, but it is stored as meta data. As such, you shouldn't need to alter the image data in order to change it.
Yes, but that's not the way any software I've ever seen saves an image. They all rewrite the entire record of data, regardless of whether the image pixels have changed or not.
Not the answer you want to hear, but the answer is no, you can't change the resolution without affecting the image. At least not when using a lossy image format. Could they, should they save an unchanged JPEG by simply copying the image data tag from the old file to the new one instead of recompressing the uncompressed image data you're working from in RAM? Yes, it should be easy to do, but no software does that.
I took a handful of test TIFF images and saved them as TIFF with LZW compression; TIFF with ZIP compression; and JPEG at the highest quality level (noted as 12 in Photoshop), baseline Standard. Note that LZW and ZIP compression in TIFF is lossless. Image quality never changes.
All sizes in MB.
Uncompressed TIFF:
File 1: 52.7
File 2: 13.8
File 3: 10.4
File 4: 8.1
TIFF with LZW compression:
File 1: 17.7
File 2: 5.8
File 3: 5.6
File 4: 5
TIFF with ZIP compression:
File 1: 15.5
File 2: 5.1
File 3: 5.1
File 4: 4.6
JPEG level 12
File 1: 7.3
File 2: 2.8
File 3: 2.5
File 4: 2
Nod goes to JPEG of course for total space savings, but you're still losing image data, even on the first save.
TIFF with ZIP is slightly better than LZW, but takes a long time to save and open, and older software titles may not be able to open them.
TIFF with LZW saves almost instantly compared to ZIP (almost the same as uncompressed) and has been around forever. Pretty much any image editor can read it.

After I covert my excel file to PDF, my images are cut off or not appearing at all HELP?!

Hello!
I am creating a Exel Work book and converting it to a PDF file (easy to share online).
Once I convert the Excel Work book, some of my images are cut off or not appearing at all.
Which I find weird because some images pop up just fine.
These images are originally flats from Adobe Illustrator I converted to pictures with Excel.
So why is that when I convert my workbook to a PDF file some images show through and others don't?
Please Help!

Images are cutted and youtube-videos are breaking down in ie7, ie8

hi muse-experts,
have the problem, that some images are cutted in ie7, ie8. the side is now working on businesscatalyst and another server.
images are cutted here on bc: http://trabbitour.businesscatalyst.com/angebote.html , http://trabbitour.businesscatalyst.com/ostalgisches.html , http://trabbitour.businesscatalyst.com/deine-trabbitour.html
the same on the other server: http://trabbitour.de/angebote.html , http://trabbitour.de/ostalgisches.html , http://trabbitour.de/deine-trabbitour.html
the videos are breaking down, by starting to scroll the side: http://trabbitour.businesscatalyst.com/trab(b)i-was-is-n-das.html
for ie adaption I inserted on all pages between html and head this line: <!— switch IE 7,8,9,10 to quirks mode —> but with or without this, the error is the same.
maybe you have an idea, what I can do and what the problem is?
thank you.

It's very difficult to say without knowing more about your system. There are a number of possibilities. First, your 13" lacks a discrete GPU, so the CPU is doing the work that a GPU would have done as far as decoding video streams, etc. Each video stream will consume considerable resources from the machine, and if you have multiple things running with video streams being decoded (for example, a browser with video Flash or cumbersome animation and iMovie running at the same time), then that may be a factor.
Additionally, it could be that you are memory constrained. You didn't post a picture of the process list from activity monitor or the memory usage stats, but you probably want to look and see what the memory and CPU usage is and who's consuming what. Some applications are pretty inefficient. For example, if you have iPhoto open and have thousands of images, the indexed metadata and thumbnails are all stored in RAM. iMovie pulls in clip thumbnail sets - (and worse, it has to do on-the-fly transcoding video assets from some cameras that don't encode the video using the parameters it expects to make indexing frames easier). Again, this would show up as periodic spikes in CPU activity for the app.
You seem to have plenty of disk space, that's not likely to be a problem.
Check if Time Machine is running. Time Machine introduces a performance impact, but it's exacerbated by the presence of frequently changed large files (e.g., you don't want Time Machine backing up your video projects while you are working on them).
Lastly, you may consider checking the console for error messages. This might reveal background processes that might be bogging down the system, or things like filesystem/disk errors. If there are errors in the filesystem, when you access certain portions of the disk, the OS and applications can slow down or lock-up as a result.

What is image dpi after "Reduce Image File Size"

Does anyone know the resulting image dpi after using the "Reduce Image File Size" command in pages? My mother is trying to prepare some things for pre-press, and can't send her document to the printing press, because the pages docs are friggin huge! I'm trying to give her the easiest option for resizing all of the many images in the document, but don't know if this is a viable option if the end product needs to be printed. I need the output to be at least 300dpi.

As fruhulda wrote, asking Pages to apply changes to the pictures isn't the good path.
In fact, it's a perfect way to get a fat file.
My practice is :
Prepare the document in Pages to define the wanted size of every embedded pictures.
Edit the picture files in a tool dedicated to this task so that the resulting files will be 300 dpis ones for the wanted sizes.
Then, replace the original pictures by the definitive ones.
In most cases, the file will be lighter than the original one and you will have the 300 dpis resolution (except if you apply shadows but it's an other story).

Setting image dpi size of tiff Image

Can anyone suggest me a method for setting the size of tiff image to 300 dpi.
I got the following code
http://markmail.org/download.xqy?id=lljtrh4jtsowwlok&number=1
But the image dpi size remains the same after this
Edited by: Priya on Dec 29, 2008 10:58 AM

Why do you think the dpi remains the same after using the code in the link?
Any given printer dosen't necessarily have to honor the dpi setting in an image format. In fact, usually the image viewer used to print the image takes control of the physical size of the image.

Creating a movie from 300 pictures

Hi,
Is it possible to create a short movie from 300 pictures which have been
created using Blender and are in PNG format (1920 x 1080 pixel).
I want to create a movie of 10 seconds (MOV, H.264, 20Mbps, 1080/30p).
(If it's too complicated to do using FCP X – is there a utility for this?)
Many thanks!

If as fox_m states the images are not named sequentially there is a neat app in the app store called Image Photo Bucket which I use to batch rename lots of images .. it can also rezize and much more
