Saving bufferedimage as 300 DPI tiff

Hi !
I have a tiff image (300 dpi) which i read process (rotate, scale, apply icc profile ...) And when I save it (see below) it ends up in a 72dpi image ... I have browsed the forum and I see lots of people have problems with this issue, but I didn't find any answer :(
Please help if you can :)

How I Write The Image
OutputStream out = new SeekableOutputStream(new RandomAccessFile(Destination,"rw"));
TIFFEncodeParam param3 = new TIFFEncodeParam();
param3.setCompression(TIFFEncodeParam.COMPRESSION_DEFLATE);
ImageEncoder encoder = ImageCodec.createImageEncoder("TIFF", out, param3);
encoder.encode(GeneratedImage);
out.close();

int[] resolution = { 150, 1};
String input = "C:/a/01.tiff";
String output = "C:/a/nuovo.tiff";
RenderedOp image1 = JAI.create("fileload", input);
TIFFField xRes = new TIFFField(XRES_TAG, TIFFField.TIFF_RATIONAL, 1, new int[][] { resolution });

tep.setCompression(TIFFEncodeParam.COMPRESSION_DEFLATE);
ImageEncoder encoder = ImageCodec.createImageEncoder("TIFF", out, tep);

How can I get 300 dpi tifs out of webex stills & then worked on in adobe illustrator?

How can I get 300 dpi tifs out of webex stills & then worked on in adobe illustrator?
I have been trying to convert images created in webex and transferred to illustrator into 300 dpi tifs. They download as ucf's when generated on white board. Or I have to upload files from other webex participants coming in at 72 dpi, converting them to something bigger in photoshop to paint in before taking them back into the webex session as a doc that then gets worked on further during the session. Later they go into illustrator for some more work with vectors. That's fine for the web but now a publisher wants them as 300 dpi tifs and I can only get things back & forth as 72 dpi pdf's. If I try to bump them up with a resample, they come out teensy weensy. What am I missing and is there any way to make them look good?

What I need is to be able to transfer the images between formats without degradation of the resolution and find ways to sharpen what I have even if I can't increase pixels. If the original I'm delivered is a 96 dpi power point slide, for example, that's what I have to work with, I'm using Illustrator to compensate with vectors. But then I still need to get it back to a 300 dpi tiff to meet the specs.

Hi pissedadobeuser,
Does this issue occur with any particular web page?
Are you able to print the webpage to 'Adobe PDF' to convert it to pdf.
Which Browser version, OS version and Acrobat version are you using?

Saving in 300 DPI?

Hi there! Wondering if anyone has an answer to my frustrating question.
I do commerical graphics for many clients, and I usually start off with a new canvas of 1200x1200 px in 300 DPI..however, when I export or save for web & devices, the resolution changes usually to 150 or sometimes even to 72 DPI wether I'm saving in JPEG or PNG. I need these graphics in 300 dpi..
I'm guessing it has something to do with compression settings, but I'm just not sure. This is a very big problem for me. Any help is greatly appreciated.
(I'm using CS4)
TIA,
~Jess

Jess,
...I usually start off with a new canvas of 1200x1200 px in 300 DPI...
No, I'm sorry, but you don't. Not in Illustrator. This statement reveals the basic misunderstanding you are stumbling over.
There is no "canvas" in Illustrator in the sense of a program like Photoshop, in which you open a "blank" document of a certain number of pixels, with each pixel just initially being white.
There are no pixels when you create a new Illustrator document. There is just a literally empty document. No pixels, no nothing. It contains no pixels at all, even if you have the rulers set to its ridiculous selection of "pixels." (You'll know why this is ridiculous in a few minutes.)
An Illustrator file contains objects, not pixels. Those objects can be of several different types. One type of object an Illustrator file can contain is a raster image, and raster images, of course, contain pixels. But until there is a raster image on the page, there are no pixels at all. And even when there is a raster image on the page, its scale (PPI) has absolutely nothing to do with the "pixels" of the page rulers.
When you export an Illustrator file as a single raster image--using either the Export dialog or the Save For Web & Devices dialog--that's when you create pixels. In fact, if there are already any pixels on the page (in raster images), those pixels are going to be resampled to new pixels to become part of the one big raster image you export.
Consider: Each raster object on the page in Illustrator is independent. Each one can have a different scale (PPI). So even if your document sizes is ridiculously called "1200 pixels x 1200 pixels", it is not. Consider this example and then tell me how it could be:
Suppose you have drawn a 4" x 4" rectangle on the empty page. You have then rasterized the rectangle at 300 ppi. Clearly, the raster image now contains 1200 x 1200 pixels. But the page rulers say it measures 288 pixels on a side. How can that be? Read on.
so a 1200 x 1200 pixel document at 300 ppi is 4 inches x 4 inches.
In Illustrator, this is absolutely not true. A 1200 x 1200 "pixel" document in Illustrator is certainly not 4 inches by 4 inches. It is 16.666 x 16.666 inches. This is because of one simple fact: The "pixels" referred to by Illustrator in its Document Setup dialog and in its rulers are not pixels at all. They are points (1/72 inch).
If you don't believe that, do this simple exercise:
Create a new document in your customary way, 1200 x 1200 with Pixels as the unit. Now stop here for just a moment, and look in that document setup dialog for where you tell Illustrator what PPI you want the 1200 x 1200 document to be. Can't find it. It's not there. There is no PPI in an Illustrator document, so you cannot say a 1200 x 1200 pixel Illustrator document is 300 ppi. (If it's anything, it's 72 ppi, but even that is skewed logic.)
Now rightClick the ruler and change the unit to inches. How big is the document?
Look at the 1" mark on the ruler. Change the ruler back to Pixels. How many "pixels" are converted to an inch? Keep doing this. Use any trick you can find in Illustrator to make its rulers convert an inch to anything other than 72 "pixels."
Now answer this: How big is a pixel?
You can't answer that question because a pixel can be any size you want it to be. It's like asking 'how big is a space?' The very fact that you can scale an image to any ppi you want (make it 1200 ppi or 12 ppi, without adding or destroying any pixels) prooves that a pixel has no fixed measure. And that's why it's ridiculous for a program like Illustrator to use "pixels" as an absolute distance measure in its rulers the same way it used inches or centimeters. It's pure nonsense.
If a pixel has no fixed measure, then how in the world can you use it as a unit of measure on a ruler? You can't; not legitimately, not in the sense of measuring dimensions of objects or pages. (Remember? Illustrator handles objects. Illustrator's rulers tell you the size of the objects.) Anywhere on that page, there may be a 1200 x 1200 pixel raster image, somehow occupying 72 "pixels" or 3000 "pixels" or 150 "pixels" of your page. Used as it is in Illustrator's rulers, "pixels" is nonsense.
Illustrator's "pixel" rulers are a complete sham. You can put a 1200 x 1200 pixel image on an Illustrator page and make it "measure" any number of sham "pixels" according to Illusrator's rulers you want. Therein lies the answer to your question:
Forget about Illustrator's rulers as being a count of pixels. It is not. It's a measure of 1/72" units (in other words, points). Do not think of the sham "pixels" on the ruler as being pixels. Think of them as being what they are: points. Then your confusion will begin to clear.
Better yet, don't use sham "pixels" as your ruler units at all. You want a 1200 x 1200 pixel raster image exported from Illustrator at a scale of 300 ppi, right?
You've been told you can't do that using the Save For Web & Devices dialog. If you've read and understood the above, you should now know that is not true. You would of course use the Export dialog to create a raster image that embeds a scale factor other than 72 PPI in the image file, because the Save for Web & Devices dialog assumes a browser which ignores the scale factor embedded in a raster image file. But for the sake of understanding, let's use Save For Web & Devices anyway:
Forget about Illustrator's sham rulers. Create your document the size you know you want it to be: 4 inches x 4 inches.
Create your artwork on the page. You can use raster images, text objects, vector objects, or any combination of those.
Now you want a 300 PPI raster export of your whole 4" x 4" page. Third grade math tells us that will require 1200 x 1200 pixels.
File>Save For Web & Devices. The Save for Web & Devices dialog opens. Select the raster file type you want, either JPEG or PNG. Go to the Image Size tab. What do you see? Original Size and settings for New Size. Original Size is 288 x 288 pixels (See? Illustrator unyieldingly considers a pixel on its rulers to mean 1/72 inch). But you can enter 1200 x 1200 (or any other desired pixel count). Click Apply.
Save. Select Images Only.
Launch InDesign. Import the image. Note the size. (Does 16.666 ring a bell?) In the Scale X Percentage field, key "4 in". (That's right, key an absolute value into the percentage field.)
You now have a 1200 x 1200, 300ppi image. You did it using the Save For Web & Devices dialog. And you didn't even use Illustrator's ridiculous "pixel" rulers.

Photoshop: 1GB - TIFF-file of 300 dpi too big?

I am starting to get grey hair with photoshop...
I have just bought a new quad core pc with 4 GB RAM, but
XP SP2 only accepts 3,25 GB. Furthermore I have installed Abode Suite
CS3 and did all the updates.
I have to merge 2 TIFF-file and make some corrections, after doing
this I generated a 300 dpi CMYK tiff-file of 1 GB. At this point PS
crashes and I can't open the file any more, it blocks when reaching +- 70%
I have selected to use the maximum memory via Photoshop preferences.
But is not possible anymore, the only thing I can do is to close photoshop via the task-manager...
Is there anyone who can help me with this matter?
I would be very greatful...
Thx,
Quincy

The others have hit on the system and set up issues but I'll a few more
notes.
1. If you're working on images this large, upgrade to Vista 64 bit and
add four more gigs of RAM.
2. What are you designing for that is creating images that large? For
the most part, I've found that people creating images that size are over
doing it with high resolutions using 300 ppi simply because they think
EVERYTHING that gets printed requires it.

Greyscale jpegs at 300 dpi

Hi -
I have just changed from using Photoshop CS3 on a PC to CS5 on a Mac. Most of my work is deisgn in Quark Xpress 7 -- using Photoshop as my image editor.
I have tried doing some work today on a greyscale newsletter design. I started this work on my old PC and am completing it on my new Mac. The photos I had already edited and saved as jpegs in CS3 on the PC show up fine in Quark at 300 dpi, but the photos I have edited today in CS5, converting to greyscale and cropping to 300 ppi will only show up in Quark as 72dpi. If I convert them to CMYK Quark will recognise them as 300dpi.If I save them as PSD files in grey they will show up as 300dpi, just not as jpegs (which I'd prefer) and bizarely when saved as TIFFs are recognised as 260dpi!
At first I thought this was a Quark problem, but it doesn't look that way as the greyscale images from CS3 are working fine.
Is there some setting in CS5 about the way jpegs are written in greyscale that I am missing?
Any help gratefully received.
Thanks,
Greg Smith

InDesign has extended it's PSD, PDF/PDP an AI support since then. 9 years! We live in 2011!
Do you know InDesign? Quark cannot export PDFs with live transparency up to today. This was possible since InDesign 2.0.
Same color management capabilites? None of them?
Layer Compss from Photoshop?
Direct support of AI files? (AI files contain a full pdf if compatible to pdf seaved.)
Fully supported RGB workflows as InDesign does?
Or do you really compare Quark's typography to InDesign's? Nested styles? Inline styles? GREP styles? Language tagged to the character, not to the paragraph or like Quark does to the whole document? Language based apostrophes?
Are you sure you want to compare? I am aware on Quark and I am aware that PDFs created from Quark are not the same as PDFs exported from InDesign. I have both applications on my computer. Do guess with which application I create only my stuff? InDesign, because I know both applications.
And if you want to compare Quark 9 to InDesign, then you should not tocompare it to version 2.0 which is now 9 years old, you should compare it to a future version of InDesign which will be available at that time. No one knows which functionality this InDesign version will have because no one knows when Quark 9 will be available. And neither no one knows what Quark 9 will can. Even if it would be announced now, Quark never fulfilled it's promises in the past to any future version.
Quark has never been able to solve problems in the past. Outside of the US is Quark way too expensive. (Sure InDesign costs much more here in Germany too.) Quark single version costs about 1.340,– Euro, InDesign 1.010,– EUR inclusive tax, or 1.126,– versus 849,– exclusive Tax (1.500 USD without tax versus 1.135,– USD). Quark has become much cheaper since InDesign hit the market here. But if you buy an Quark update you cannot be sure that the delivered serial will work. With the previous version it took me 4 months to get a working serial. Everyday phone to Quarks support. Expensive phone numbers outside Europe, because they are in Switzerland. (CH is not part of the European Union.) Virtually no one here in Germany buys Quark to create new art with it. It was only bought to use old files newer computers or because some partners deliver files which have to be opened. Have you ever tried to contact Quark's support? Maybe that you get one on the phone, but you will never get help.

Processing images as 300 dpi jpegs, comes out at 72 dpi.

I've seen two other posts with the same problem with no answer, so I thought I try as well. I am using Ap 2.1. I've processed the images in both the preset jpeg original size with the edit to 300 dpi. I've also made a custom preset with 300 dpi jpegs. Both times the images open in PS at 72 dpi. I processed them as tiffs at 300 dpi and they open in PS at 300 dpi just fine.
I've tripled checked the file-export-versions-JPEG original size-edit-300dpi.
any ideas what's up?

J,
I am repeating a post I made in another topic about this issue -- I would appreciate your thoughts:
I conducted a test that may or may not tell us something, but: I had a project with an imported photo scanned at 600 dpi and saved as a .psd at the time of the scan, before importing into Aperture. If I export that photo as a .psd, then PS will open it with a dpi of 72, but GC will open it with a dpi of 600. However, if I export that photo as a .tif, then both PS and GC open and report it to be 72 dpi?
I am not sure, but I think this is an indictment of Aperture?
Please tell me about the possible impact at any printers you use, since if the print size is specified, and not pixels have been lost, the image will print as you intend? I have some reports this has been seen with iPhoto, but ultimately not an issue, but I have not research with any printers.

Save 300 dpi jpegs

I have a tiff file of a painting I scanned at 300 dpi. It's original image size when I open it is photoshop is 57.8 MB, 18" W by 12.477" H, Res 300. I need to resize it and send it as a 300 dpi jpeg. I have started in the image size dialogue box and just change the W to 11.25. That automatically changes the H to 7.798 and the res still says 300. The file size reduces to 22.6 MB. I click ok and then go to save as and choose jpeg. In the jpeg box I chose 12 Max and baseline standard and click ok. The saved file is reduced to 8.5 MB. When I open it in photoshop, it opens at 300 dpi when I look in the image size box. However, when I send it to someone else and they open it, the file is only 72 dpi. What am I missing to get the file to save at 11.25 inches, jpeg, but remain 300 dpi?
Thank you.

I have a tiff file of a painting I scanned at 300 dpi. It's original image size when I open it is photoshop is 57.8 MB, 18" W by 12.477" H, Res 300.
That means you image is 18x300=5400px wide and 12.477x300=3743px high widthxheight=numbed of pixel 3 bytes per pixel for 8bit color 5400x3743x3=60,636,600 which is close to Photoshop 57.8MB estimate or the Tiff file is 57,8MB.
I need to resize it and send it as a 300 dpi jpeg.
Then all you have to do is resize the open document and save a jpeg file.
I have started in the image size dialogue box and just change the W to 11.25. That automatically changes the H to 7.798 and the res still says 300.
That means you also have RESAMPLE and Constrain checked in the Image Size dialog bottom control section and some interpolation method is set. Photoshop will reduce the number of pixels you have for the image. When you click on OK Photoshop will generate a new image that is 11.25x300=3375px wide and 7.798x300=2339px high
The file size reduces to 22.6 MB.
The file is not changed when you use Image Size. The Tiff file remains as it was before it was opened. Photoshop is a document editor not a file editor.
I click ok and then go to save as and choose jpeg.
When you use "Save as" and use the pull-down menu and select Jpeg you will be saving a new file and not be over writing the tiff file.
In the jpeg box I chose 12 Max
That is a quality setting the higher the number (Max 12) the better the file quality will be the file will be less compressed then when lower quality setting are used. You would be hard pressed to see any image quality difference between quality 10 file and quality 12 file. The quality 10 file size will be quite a bit smaller then a quality 12 jpeg file.
and baseline standard and click ok. The saved file is reduced to 8.5 MB.
The new jpeg file size is a product of the jpeg quality setting and how well the image data compresses. Size can vary all over the place. Images with lots of fine details will be larger then images with little detail. An image of a white wall will compress much smaller the an image with the same number of pixels that has a lot of details like an image of a cross word puzzle.
When I open it in photoshop, it opens at 300 dpi when I look in the image size box.
Correct you did not change the resolution when you resampled the image.
However, when I send it to someone else and they open it, the file is only 72 dpi. What am I missing to get the file to save at 11.25 inches, jpeg, but remain 300 dpi?
If when they open the file the receive they see an image that has a 72dpi resolution. It means either what you used to send the file resized the the image and sent a different file or what was used to receive the file resized the image and saved a different file. Or the image was resized by the image processor the user used to open the file either during open or after it was opened. For example if the user received the file you saved and sent 3375px wide and 2339px high and 300DPI and opened it in Photoshop and Photoshop is set to open Jpeg images through ARC the users ACR default workflow setting could be set to open image at 72DPI. An image dpi is a setting the image may still be 3375px wide and 2339px high however set to 72 DPI the print size would be 3375px/72=46.875" wide and 2339px/72=32.486" high using Image size changing itr 72dpi print resolution to 300dpi with RESAMPLE NOT CHECK would return it size to 11.25" x 7.798" at 300DPI.

PDF does not display 300 dpi images in Safari only

I have a dynamically generated PDF that contains a 300 dpi image. The image added can be one of several that the user selects. On all other browsers the pdf renders fine. On Safari only, seemingly in all modern flavors of OSx and Safari, the images begin to print and then stops printing the actual image and grey is printed in the remaining space the image would take up. To make it more fun one of the images renders fine. It is the 3rd smallest image and the 2 smaller ones do not render so it does not seem to be size related. Hoping someone here has seen this before.
This is a screenshot to use as an example:
The folding instructions graphic is also 300dpi.

Thanks Hackintosh.
It prints as it views, as a corrupt jpeg. I also dug into console and it confirmed there was an error about a corrupt jpg. The most interesting thing is if I open the bad pdf in Photoshop the whole image is there with no signs of corruption. This leads me to believe it's something with how OSx and/or Safari are rendering the jpgs. Another curious sidenote, Safari on Windows works fine but if you save the pdf, move it to a mac and open it, you get the corrupted jpg again.
I think I'm going to try and stop swimming upstream now. At the end of the day I don't care if the images are pngs, tiffs, or eps. I'm going to try feeding a few different formats and see if that doesn't fix the problem.

How do I create a 300 dpi PDF from a Word 2003 file?

I need to convert a Word (2003) file to a High-res PDF file for the printers. They have requested 300 dpi.
I have Adobe Acrobat 9 Pro (trial version).
The file contains a number of pictures in jpg format. Most of these are pretty high resolution. The document printed in Word on a laser printer looks fine.
I did try saving the file a a PDF file, and that did work, however it was low resolution. There must be some settings I have to change. How do I set things so it will creat a high resolution PDF file?

There is no such thing as resolution of a PDF file. Text and vectors in PDF are preserved and get scaled depending on the device on which PDF is shown.
Images in PDF do have a resolution that you can set when creating PDF. When printing your file from Word:
After File>Print, select printer properties.
In "ADobe PDF Settings" tab, you will see "Default Settings" - click the Edit button next to it.
In the Images pane, select your desired resolution.

Save PDF to Folder as Jpeg/300 dpi

Question about exporting custom book design into Jpegs/300 dpi. I do it, it seems to be working and then once it stops I can't find the file with the jpegs of the book design. Not sure if it's saving and if it is where it's saving to? I went into automator (which I know nothing about) and when I run the 'save PDF to folder as jpeg" action, I get an error message. Help! Thanks in advance!

Installing Aperture again will not affect your library, so there is no risk doing that.

Copy a 300 dpi photo onto a 100 dpi background

I'm creating a collage of photos (mockup, right now). The background on which those photos will be added as layers is at 100 dpi.
When I copy a 300 dpi photo that shows up on my screen at 100%, and paste it on the background (also viewed at 100%) — I would expect the 300 dpi pasted photo to render on the 100 dpi background at a 300% ENLARGEMENT... But it shows up at the same size it was rendered in it's own window... That doesn't make sense to me... Am I suppose to first lower the resolution of the 300 dpi photo to 100 while enlarging it's physical size 3 times?
I must be missing something here...
Thanks...

Photoshop document changes to 72 dpi from 300 dpi when receiver opens it.

I created an ad for the newspaper at 300 dpi. I emailed it and received a call it was at a low res of 72. I know I created it and saved it properly. I researched and found I should uncheck the resampling box when saving the document. I did that and resent, same issue.
I have recreated the ad over 20 times and sent it all with the same issue. I just hung up from Adobe after spending over an hour on the phone with them, having them take over my computer, e-mail it himself after creating his own 300 dpi document and the same result. Basically, Adobe is telling me it isn't their problem, it is my server. I sent it from Yahoo and Microsoft and still 72. Even sending as Tif, 72 dpi.
I am at a loss. I don't know what else to try and this ad needs to be in the newspaper in 2 days.
Does anyone have a suggestion? I'm desperate.
Thanks,
Mary

It is very usual for many applications (such as the receiving party must have) to open JPEGs at 72 ppi by default but without resampling, i.e. maintaining the exact number of pixels, so many pixel wide by so many pixels high.
It is then a trivial matter for the recipient to change it back to 300 ppi without resampling to go back to your original.
Incidentally, it's ppi not dpi.
The fact that you say the resolution and the size (pixel dimensions, or so many pixels wide by so many pixels high) does change makes me suspect that you may be using Apple's "Mail" program to email your files. Mail is notorious and (in)famous for reducing the size of your attachments at will if it deems it appropriate or necessary, as in "nobody in his right mind would want a JPEG that big!" Grrrrrr…
Ideally, you should switch to a decent email program. I use MS Entourage, part of MS Office.
The workaround is to archive or "zip" your image files before attaching them to Apple's Mail, so that you end up with an archived or zipped file that Mail can't touch, as it won't even know it's an image file.
If you are not using Mail, you'll have to continue troubleshooting.

Why did I get 72 dpi solutions in AI CS5 instead of 300 dpi in Photoshop CS5!

Dear all!
I have done my file in Photoshop with 300 dpi. I have finished it and then saved it as EPS because I would like to open it in my AI CS5.
So I go to File>Open the EPS File in AI CS5. I get it with 72 dpi file in AI CS5 when I check the resolution in Effect>Documents Raster Effects Settings. Why did I get 72 dpi file in AI CS5 instead of the original file which is really 300 dpi in Photoshop?
Will it change the quality if I change from 72 dpi to 300 dpi as I wish to in the Documents Raster Effects Settings?
Please help to explain in details if possible.
Thanks a lot and best wishes.
I am looking forward to hearing from you.
My best regards,
LUCK

Luck,
To see the use the raster image in its right size along with other objects, scale it (down) to match. To go from 72 to 300 PPI you need a factor of 0.24 (proportionally), you may use multiplication by 0.24 in the Transform panel or Object>Transform>Scale with 24% .
It means I must change resolutions in Document Raster Effects Settings if I have effects raster effects created within Illustrator. Is it right?
If (and only) if you wish to have the effects at the same resolution as (one of) the raster image(s). This will depend of the actual effect, but for many effects, yes (you will have to choose one resolution if the document contains more than one).
Illy always sees raster images at 72 PPI, unless she is told otherwise.
