Overprint for tiff images

hello everybody,
I am pretty new to indesign and i don't understand how can i place a cmyk tff image in overprint.
I understood how to do it for stroke and fill colors, but not for images...
anybody can help?
thanks

Multiply is similar to overprint, but out of the blend modes Darken is the most similar to overprint (although it still isn't exactly the same)
With darken blend mode you are also less likely to end up with too much ink in the dark areas of the image (although it can still happen). Bset way to check this is to use Separation Preview in InDesign and look at the color percentages in the dark areas.
The difference between darken and multiply is, with multiply a single ink can compound. The formula is Color 1 % + Color 2 % - (Color 1% x Color 2 %) = Blend %. So 25%M multiplied over 50%M = 62.5%M.
With darken blend mode it defaults to the darker value. So 25%M darken over 50%M = 50%M.
When overprint is applied and only one ink is involved, it defaults to the top color. The reason is an ink cannot overprint itself. So 25%M overprint over 50%M = 25%M
Another key difference between multiply and darken comes when you have spot colors. If you have a spot color element set to darken over a CMYK image, the image CMYK values are not affected whatsoever. But if you set the spot object to multiply, the CMYK values underneath the spot will increase. So in that case, Darken behaves just as an overprint, while Multiply does not.

Jpeg compression for tiff image (nt gettin a view of jpeg compressd pages)

Hi All,
I have a problem of jpeg compression inside a tiff file. When I convert no. of pages in a multi-page tiff file I m not getting a view of jpeg compressed pages. I convert black and white as well as gray scale jpeg images inside the tiff file. I used Compression Group4 for black and white image and JPEG compression for gray scale image. Also set the dpi of each page. But most of the viewer doesnt support my jpeg compressed pages. When I set the quality of jpeg images to 0.1f that time I m getting a view of particular images for some image viewer.
My requirement is to show the jpeg compressed image inside the IMAGING PREVIEW 2.5 VERSION. But it doesnt support for my output tiff. As well as cant get properties of that page inside the Fax viewer except Resolution 200x200 dpi.
     If anybody has any idea to compressed jpeg image inside the tiff file, please tell me how I can compress the gray scale image using jpeg compression.
Thank you in advance

Hi Maxideon,
Thank u 4 ur immediate reply. But my requirement is, to show d tiff file only in IMAGING PREVIEW 2.5 VERSION. I tried lots but didnt manage to get a view of JPEG compressed page. I think somewhere I m doin wrong. Somewhere I wrote wrong code, cause d properties of jpeg compressd images also not getting in Fax Viewer except DPI. I change the BaselineTIFF Tags of JPEG compressed image, but cant manage output yet. I think d problem create at d time of metadata writing. My problem is tht, tiff created using sum other soft. is suppported by IMAGING PREVIEW 2.5 VERSION, y nt mine?
Here is my code for BaselineTIFFTagSet:
if(isBinaryImage) {
             // resolution unit
             rootTiffIFD.addTIFFField(new TIFFField(base.getTag(296), 2));
             // bit per sample
             rootTiffIFD.addTIFFField(new TIFFField(base.getTag(258), 1));
             // compression
             rootTiffIFD.addTIFFField(new TIFFField(base.getTag(259), 4));
             // rows per strip
             rootTiffIFD.addTIFFField(new TIFFField(base.getTag(278), bImageImage.getHeight()));
        } else {
             rootTiffIFD.addTIFFField(new TIFFField(base.getTag(296), 2));
             rootTiffIFD.addTIFFField(new TIFFField(base.getTag(258), 8));
             rootTiffIFD.addTIFFField(new TIFFField(base.getTag(259), 7));
             // thresholding
             rootTiffIFD.addTIFFField(new TIFFField(base.getTag(263), 3));
             rootTiffIFD.addTIFFField(new TIFFField(base.getTag(278), bImageImage.getHeight()));
        }     If u have any idea 4 write a metadata of jpeg page wid jpeg compression, can u plz suggest me hw to write a metadata 4 jpeg image? Which Baseline Tags r needed to set d jpeg compression?
Thank you

MIME Content Type in HTTP Headers - They don't exist for TIFF images

Hello,
I think this may be a bug...
In an effort to stop client browsers from attempting to render TIF images served up from UCM 11g, I would like to change the MIME Typte to: application/octet-stream
Supremely, a browser would see this in the HTTP header and simply provide the "OPEN or SAVE" dialog.
Seems easy enough - from the UCM Configuration Manager, I can set/edit all the mime types I want. I did set .tiff and .tif to application/octet-stream. Apparently Weblogic does NOT honor these settings.
When I click on a PDF file, I get: application/pdf
When I click on a TXT file, I get: text/plain
When I click on a TIF file, I get: NOTHING - no mime type specified in the HTTP header at all.
Does anybody know where in the stack of Weblogic/UCM 11g that mime types are set? Does anybody know why I'm not seeing ANY mime type when I click on a tif?
Please let me know.
Thanks!
JDM

Yeah, that does seem a bit unwieldy. Try the following instead:
Navigate to the "<Middleware_home>/user_projects/domains/<yourdomain>/config/" directory and there create the following file :
mimemappings.properties
In this file add the below mapping :
tiff=application/octet-stream
Save the changes , restart UCM server and then test to see if the issue still shows up .

I use Photoshop Elements 11 to print panoramas. Works for jpeg images but not tiff. Suggestions?

I use Photoshop Elements 11 to print panoramas. It works for jpeg images but not for tiff images. Seems strange because PSE11 manages tiff images in all other processes. Anyone fared better?

Thank you for your trouble.
My images are not usually layered and the particular case I am about to quote, it is not. The dimensions are 10,546 x 2,790 and the image has 16.7 mbs. I use 8 bit colour. When I set up the print screens for tiff, everything is normal until I get to the last screen with the image set upon the photo paper. Then the paper size indicated with the image refuses to budge from the A4 size, so the panorama gets printed on that. I consulted the Adobe chat line and the expert could 't get it to work either. So he came to the conclusion that the tiff capability had not been extended to printing panoramas. In seeking advice, I thought someone might refer me to an updating patch!
Well done! You have confounded the system! I could not find any control that would override the setting.

How to display TIFF images?

Hello all.
My web application needs tiff images viewer with a very primitive functionality like zoom. I'm a new in working with graphics and it seems like java.awt.image package doesn't support TIFF images format. From searching this forum I understood there are 3 party products like JAI to work with those images.
Can somebody send me an example of how to read and display those images with zooming option; and/or how to convert from tiff to GIF/JPG formats (which also can be a solution for me).
If somebody has a ready applet that implements the required functionality and can share it with me, I would appreciate it very much.
Email: [email protected]
Thanks in advance.

I am also looking for Tiff Image zooming functionality. Please through your ideas or suggestions. I will appreciate your advises. If anyone has developed API, Please let me know, I am ready to look in to it. I will appreciate your quick response.

Reading in data from IPTC keywords from a CSV and writing those keywords to TIFF images

Hi All,
I have a client that I'm working with that has a specific request for a script, or possibly a plugin. I'm interested in both hearing if folks here think it is feasible, and also if anybody here would be interested in doing the work on this.
I have never done PhotoShop scripting and I think it would be the best use of resources to subscontract this out, unless it proves exceedingly easy. The kind of thing someone can do in a single forum post. In which case, if you do that for me, I'll be sure to get you something for your time as a thank you :-)
Here's the situation: my client runs a niche stock photography business and deals with tens of thousands of hi-res TIFF images. Each of those images is assigned a list of keywords, a serial number, the photographer who took the picture, the date, the location, etc. Lots of information. He's got a FileMaker Pro database where he stores all that information.
Some of those bits of information he also wants in the IPTC data for the TIFF image. The keywords in particular are the main field he's interested in getting into the TIFF images.
He has been dealing with this process manually so far in Bridge CS4. He goes to each image, and copy/pastes the keywords into the IPTC data. But he's interested in figuring out a better way to do this. He can get a spreadsheet that has all the keywords and filenames out of his database, and what we'd like to do is have a Photoshop script that can read in that CSV file, and then scan a directory for TIFF images with those filenames, and write the appropriate keywords onto those TIFF images.
Is this possible? I'm eager to hear feedback on this. Right now he's got a slew of 1800 images that he got on slide film from photographers, and has scanned, but hasn't written the IPTC keywords to yet. If we can use this process on those, that would be great.
-Josh

Hi Paul and Mark,
That link Paul posted looks very promising. I'll have to test it out.
One question: is there anywhere I can get Adobe Bridge CS4? Since that's what my client has, that's what I'd like to test with. I've been looking but can't find anything but the most recent version (CS5) for trial download.

Java returning incorrect values for width and height of a Tiff image

I have some TIFF images (sorry, I cannot post them b/c of there confidential nature) that are returning the incorrect values for the width and height. I am using Image.getWidth(null) and have tried the relevant methods from BufferedImage. When I open the same files in external viewers (Irfanview, MS Office Document Imaging) they look fine and report the "correct" dimensions. When I re-save the files, my code works fine. Obviously, there is something wrong with the files, but why would the Java code fail and not the external viewers? Is there some way I can detect file problems?
Here is the code, the relevant section is in the print() routine.

Figured it out. The files have a different vertical and horizontal resolutions. In this case the horizontal resolution is 200 DPI and the vertical is 100 DPI. The imgage width and height values are based on those resolution values. I wrote a section of code to take care of the problem (at least for TIFF 6.0)
 private void setPageSize(int pageNum) throws IOException
 IIOMetadata imageMetadata = _reader.getImageMetadata(pageNum);
 //Get the IFD (Image File Directory) which is the root of all the tags
 //for this image. From here we can get all the tags in the image.
 TIFFDirectory ifd = TIFFDirectory.createFromMetadata(imageMetadata);
 double xPixles = ifd.getTIFFField(256).getAsDouble(0);
 double yPixles = ifd.getTIFFField(257).getAsDouble(0);
 double xRes = ifd.getTIFFField(282).getAsDouble(0);
 double yres = ifd.getTIFFField(283).getAsDouble(0);
 int resUnits = ifd.getTIFFField(296).getAsInt(0);
 double imageWidth = xPixles / xRes;
 double imageHeight = yPixles / yres;
 //if units are in CM convert ot inches
 if (resUnits == 3)
 imageWidth = imageWidth * 0.3937;
 imageHeight = imageHeight * 0.3937;
 //convert to pixles in 72 DPI
 imageWidth = imageWidth * 72;
 imageHeight = imageHeight * 72;
 setImgWidth((int) Math.round(imageWidth));
 setImgHeight((int) Math.round(imageHeight));
 setImgAspectRatio(imageWidth / imageHeight);
 }

TIFF images are displayed as thumbnails but will not open for editing

I have noticed a problem with my iPhoto 7.xx
iPhoto displays the thumbnail of TIFF files but when it is selected (for editing as an example), iPhoto displays a grey circle with a black question mark. This happens with TIFF images from any source (multiple camera, scanner, etc). The TIFF files are NOT in raw format.

Open the file with Preview and do a Save As. Either change the format or keep the tiff. That should fix the files so they can be viewed normally in iPhoto. If the problem is due to an alpha channel in the file this will fix the problem.
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 6 and 7 libraries and Tiger and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar.

Acrobat 7.0.5 for Windows -- Problem creating a PDF from a TIFF image

I have a user who is attempting to create a PDF from a TIFF image using the Adobe PDF print driver (Acrobat 7.0.5). His computer is a 3.4 GHz Intel Pentium 4 with 1 GB of RAM. His operating system is WinXP Pro SP2. The TIFF file he is trying to convert is about 2000 pages long. Is this even possible given the hardware and resources I've described?

Sorry, I should have been more explicit...The TIFF image is a multi-page image and is stored in a database here at our office. The user has a proprietary (internally-coded) viewer that's used to open the image from the database, and there's no way to save the image locally. The user wants to be able to search within the image, so he converts it to a PDF. Ordinarily, this works very nicely, but this is his first time trying to do it with an image of more than 1000 pages length.

A generic error occurred in GDI+ while assing tiff image file to Bitmap and Image

Hi,
I am getting "A generic error occurred in GDI+" error while reading the tiff image file to Bitmap or Image.
Below is my sample code.
string filePath=@"c:\Images\sample.tif";
Bitmap bmp=new Bitmap(filePath); // here getting exception
int totalpages=bmp.GetFrameCount(.....);
etc......
I tried using Bitmap.FromFile() and also from FromStream() even for Image also but there is no use.
Moreover i m having full permissions for the file path and the tiff file is having multiple pages.
Can anyone help me to solve this issue please.
Thanks & Regards,
Kishore

Make sure that the Tif file is valid (can other software open it)? If you are able to save a Tif using GDI+, try saving that Tif, then opening it. Part of me wonders if there is something about that specific Tif that GDI+ doesn't like.
You could also try using WIC to open the TIF, perhaps you would have better luck there.

How can I merge two TIFF images in one...?

I need some help please, I am looking for a way to "resize" black & white single TIFF images.
The process I need to do is like cutting a small image and paste it over a new blank letter-size image (at 300 dpi), like a template.
Or better yet, is there a way to do something like this...?
Open image...
image.*width* = 2550;
image.*height* = 3300;
image.save();Some APIs and topics in the internet do or talk about resizing, but the final images get stretched or shrinked and I need them not to do so at all.
Also, I do not need to display the images, only to get the TIFF images processed and saved back to a file.
How can I do this with Java and JAI? Unfortunately I am almost new to this and I don't know how difficult it might be to deal with images.

If 2550 x 3300 isn't the original aspect ratio of the image, then the image is going to looked streched or shrinked in at least one dimension. There is no way around that. It would be like resizing a 2 pixel by 2 pixel image into a 3 pixel by 6 pixel image. The image would look like it's height shrunk or it's width stretched. Had I resized it to 3 pixels by 3 pixels or 6 pixels by 6 pixels, though, then it wouldn't look shrunken or streched.
Open image...
image.*width* = 2550;
image.*height* = 3300;
image.save();*1)* To open a TIFF image you can use the javax.swing.ImageIO class. It has these static methods
read(File input)
read(ImageInputStream stream)
read(InputStream input)
read(URL input) You can use which ever method you want. But first you need to install [JAI-ImageIO|https://jai-imageio.dev.java.net/binary-builds.html]. The default ImageReaders that plug themselves into the ImageIO package are BMP, PNG, GIF, and JPEG. JAI-ImageIO will add TIFF, and a few other formats.
The downside is that if clients want to you use your program on their machine then they to will need to install JAI-ImageIO to read the tiffs. To get around this, you can go to your Java/jdk1.x.x_xx/jre/lib/ext/ folder and copy the jai_imageio.jar file (after you've installed JAI-ImageIO). You can also obtain this jar from any one of the zip files of the [daily builds|https://jai-imageio.dev.java.net/binary-builds.html#Daily_builds]. If you add this jar to your program's classpath and package it together with your program, then clients won't need to install JAI-ImageIO and you'll still be able to read TIFF's. The downside of simply adding the jar to the classpath is that you won't be able to take advantage of a natively accelerated JPEG reader that comes with installing JAI-ImageIO (instead, ImageIO will use the default one).
*2)* Once you've installed [JAI-ImageIO|https://jai-imageio.dev.java.net/binary-builds.html] and used ImageIO.read(...), you'll have a BufferedImage. To resize it you can do the following
BufferedImage newImage = new BufferedImage(2550,3300,BufferedImage.TYPE_BYTE_BINARY);
Graphics2D g = newImage.createGraphics();
g.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR);
g.drawImage(oldImage,0,0,2550,3300,null);
g.dispose();Here, I simply drew the old image (the one returned by ImageIO.read(...)) onto a new BufferedImage object of the appropriate size. Because you said they were black and white TIFF's, I used BufferedImage.TYPE_BYTE_BINARY, which is a black and white image. If you decide to use one the BufferedImage types that support color, then a 2550x3330 image would require at least 25 megabytes to hold into memory. On the other hand, a binary image of that size will only take up about one meg.
I specified on the graphics object that I wanted Bilinear Interpolation when scaling. The default is Nearest Neighbor interpolation, which while fast, dosen't look very good. Bilinear offers pretty good results scaling both up or down at fast speeds. Bicubic interpolation is the next step up. If you find the resized image to be subpar, then come back and post. There are a couple of other ways to resize an image.
Note, however, if 2550 x 3300 is not the same aspect ratio as the the TIFF image you loaded, then the resized image will look shrunk or stretched along one dimension. There is absolutely no way around this no matter what resizing technique you use. You'll need an image whose original dimensions are in a 2550/3300 = .772 ratio if you want the resized image to not look like it's streched (you can crop the opened image if you want).
*3)* Now we save the "newImage" with the same class we read images with: ImageIO . It has these static methods
write(RenderedImage im, String formatName, File output)
write(RenderedImage im, String formatName, ImageOutputStream output)
write(RenderedImage im, String formatName, OutputStream output)You'll suply the resized BufferedImage as the first parameter, "tiff" as the second parameter and an appropriate output for the third parameter. It's pretty much a one line statement to read or write an image. All in all, the whole thing is about 7 lines of code. Not bad of all.
Now as for the 300 dpi thing, there is a way to set the dpi in the Image's metadata. I'm pretty good at reading an image's metadata, but I've never really tried writing out my own metadata. I know you can set the dpi, and I have a somewhat vague idea how it might be done, but it's not something I've tried before. I think I'll look more into it.

How do I Convert a Tiff image to a jpeg without being FORCED to 8-bit Color?

I am an Artist. I have High quality TIFF images. When I convert the tiffs to jpeg it forces me into 8-bit color automatically. (Forget about 32bit - it will not allow me to jpeg that at all) The only way I can get back to 16bit color is to use the already SMAshed file and bring it up to 16bit. THIS makes NO sense. Once the jpeg is smashed, HOw in the world is it supposed to convert up again. ?? Then even though it says you converted the file to 16 -bit , the metadata refers still to the file as 8-bit.
On top of all of that confusion, One picture, for example, when supposedly converted to 16bit, gets much BRighter then even the original Tiff image. It looks good on one hand and over exposed on the other. I assume that is photoshop throwing in fake resolution, am I right?
Am I wasting my time with this imaginary 16bit conversion?
Is there ANY way to take that original Tiff image and convert it to 16bit jpeg without the Default 8bit? I have been trying all kinds of things. I even have asked my web guy. My web guy says that 8-bit is unexceptable for printing, even for web.
Could this have anything to do with my computer and scanner?
I have the iMAC OS X 10.8.3 (3.2 GHz) 8 GB memory.
And I also have an Epson Expression 10000XL graphic arts scanner capable of scanniing at 48bit color.
This color stuff Really matters! It MATTERS! I HAve FINE art files. I am already losing so much quality with the jpeg conversion. (which I am required to do for SmugMug, in addition to compressing all my files to 50mb or Under)
Anyone who knows anything that could help me would be much appreciated.
Aloha,
-Melissa

First of all jpeg is 8 bit only there is no way to save as a 16 or 32 bit jpg, just does not exist. Secondly people print in 8 bit all the time and most if not all web graphics are in 8 bit as that is the only way to view it as there is no 16 bit or 32 bit monitors to view it. All but a few pro monitors are 8 bit monitors.
If you care about the color gamut and want the full range of color that 16 and 32 bit provide, then why jpg? Jpg by its own nature throws out color just to compress, thats why it is popular on the web, because of its small file size not its quality. If you need 16 or 32 bit for anything it must be in a format that supports that color depth.
That being said a jpg image at 8 bit will display 16+ million colors, 256 shades of red, 256 shades of green and 256 shades of blue.
Now here is where I think your bit information is off. a jpg image is a 24 bit image that will produce 8 bits of red, 8 bits of green and 8 bits of blue.
The 8, 16 and 32 are per channel not total color information.
If the overall image was 8 bits, the image would be gayscale.

Trying to display multipage tiff image getting error

How to edit 16bit TIFF image sequence file in FCP?

Dear all,
I have a number of 16 bit TIFF image sequence files (2048 x 1024 resolution) - some of them are RED footage, and others came directly from our f/x guy. We are going into a color correction session in a post house and we've been asked to provide a sequential 16 bit TIFF image sequence of the edited time line.
I need to do a cross dissolve b/w most of the clips I have. I have created image sequence QT movie (reference files) from the TIFF images. Though they play fine in QT player, when I try importing into FCP, I am met with a "general error". I tried both dragging it into QT, as well as File --> Import.
I am wondering what can I do to get these clips into FCP in order to apply the cross dissolve transitions I need. Is this a problem relating to the 16bit nature of the TIFF files?
I tried exporting the TIFF image sequence standalone QT movie, and those imported fine. However, I have a feeling that the standalone movie conversion also decrease my bit depth from 16 to 8. (When I do my final TIFF output from FCP after dissolves / transitions had been applied, each TIFF file is now 8 MB instead of 12 MB, hence my suspicion that the bit depth is adjusted).
Are there any settings I am missing, or does FCP simply don't support 16 bit image sequence reference file. As a test, I had also converted all my TIFF to jpg, and created jpeg image sequence reference file. These reference QT file can be successfully imported to FCP and I can edit them as if they are a clip.
If FCP is not able to handle these files, what are my other options? After Effects?
Any help is appreciated.
Thank you.

As far as I know, both FCP and Color only support up to 10 bit color, which is 1024 levels for each color channel, more than enough for avoiding color banding.
If you need 16 bit for sure, I believe AE will support 16 bit output. Another 16 bit application would be the extended version of Photoshop, which has some limited time line capability.

Error encountered while reading TIFF image, Image may be damaged of incompatible. Resave the image w

I am currently running CS3, windows XP, service pack 2, with recent update, 5.03 installed today.
I just opened a 500 page document not in sections where 90% of the document is a placed PDF.
The PDFS were placed using a sample Script that came with Indesign, that instructs the PDF to automatically flow each page after another.
When scrolling through quickly in the pages pallette, I get the follwing error:-
"Error encountered while reading TIFF image, Image may be damaged of incompatible. Resave the image with different settings and try again."
I click OK.
Then I get the following error.....
" Could not complete request because of database error. The File "ABC.indd" is damaged (Error Code: 3).
Click OK....
Then I get the following error....
Adobe Indesign is shutting down. A serious error was detected. Please restart Indesign to recover work in any unsaved Indesign documents.
Then I get the error.......
Indesign.exe has encountered a problem and needs to close. We are sorry for any inconveneince.
And I have two buttons to click....
Debug or Close.....
If I click Debug, it closes Indesign.
Within this window there is also a window to gather further information....I click it and it tells me...
"Indesign.exe....Error Signature AppName: indesign.exe AppVer: 5.0.3.662
ModName: public.dll ModVer: 5.0.3.662 Offset: 0002e19a"
To view technical inforamtion about the error report, clikc here....
"Then it creates an error report and tells me where the report is located along with a scrollable window of 0xc0000005 and heap of zeros."
The report conatains a whole heap of CHECKSUM ERRORS.
CAN ANYONE PLEASE HELP??
I had these errors before updating to 5.03 and the patch hasn't rectified anything!!

Open the .inx file in CS3 (that's what you have, right?) and save as a new .indd.
I'd also be tempted to open the tiff in Photoshop and do a save as to re-write it.
Let us know if it helps.
Storing files on the network leaves you more open tot he risk of file damage during transfer and save operations.
