We produce a catalog with thousands of greyscale eps images. These were produced on OS X and Photoshop CS. The printer tells me when they try to open the images in Photoshop 7 (OS 9) that it wants to Parse the eps file and it turns it to CMYK. It is even currupting the file alot of the time.

Any Ideas?!?

Why is the printer opening the images?

I would look for a new printer if I were you.

I guess the other question is why are you using .eps files they are trouble waiting to happen. I would use .tif or PSD.

The images where color and not supposed to be. Also there rip (Scitex) was displaying corrupt images in the ripped file.
I have to use eps files right now till I can convince the programmers to make our data base management software handle tiff files.
Is there a web site that can show them the advatages of tiff over eps files? Like size of the file is a big one that could make us switch.

I have the same problem. I think it’s a bug with Photoshop 6. You should tell your coworkers to upgrade.

Byron,

There is a bug in Photoshop 6.x only which prevents some images cretaed in Photoshop 8 from opening properly in 6.x.

It’s in the FAQs.

If you try to re-open EPS files which contain vector objects, they will be rasterized. This sounds as if it is what is happening in your case.

I would do three things:

Save your files as .PSDs;
Use InDesign for Page layout; and
Go to a different Printer.

When you open an eps file don’t you have a choice how it will raster?

mode.

Res

that sort of thing?

A Photoshop EPS which is free of vector objects will open in Photoshop without any warning dialogs about rasterizing.

But an Illustrator EPS, a QXP page saved as an EPS, or a Photoshop EPS which contains type or vector objects, will prompt the rasterization dialog to appear—which gives you the chance to choose both the color space and the resolution that you want to apply to the file.

Yes thanks all. I am aware that files from other programs and vector included files will ask to be rasterized but these are just photos from CS turned to greyscale in CS. I am wondering if I found a bug between files produced in CS and opened in Phtoshop 7 or 6.

It is probably Photoshop 6 that is causing the problem.

I would never use an .eps for just an image file.

what is the point.

And again why is the printer opening the files if they were to contain vector elements it would raster them.

I get a new printer.

I agree with Buko.

Back in the bad old Quark Ages, I used to use EPS for all CMYK images because QXP couldn’t "get at" them and muck them up with its apology for Color Management (like it could with tiffs).

Now we have InDesign and PDFs.

PDF’s, if created incorrectly, are just as bad, if not worse as incorrectly created layout files.

Correctly created PDF’s are great.

Who has time to do it right when you can do it twice.

I am working on sending to press a four color calendar/menu for school. The school sent everything in excel
the top half is on sheet 1 and covers aprox 35 cells across The bottom half is on sheet 2 and covers 5 cells across.

I have tried various ways to get this to a pdf file with everything joined together.

The biggest problem when I get it there is that the separations are wrong and there is a lot of pixalation which makes the finish product (negatives) fuzzy.

Any help on the steps to get a good copy would help a lot.

BTW 3 of the excel docs were not broken into sheets and I saved them as pdf’s and they printed great.

It the problem seems to be when I try to join the files in photo Shop and then re-saving them to pdf.

Thanks, in avance.

Excel!

You are pretty much screwed.

You can try and export an EPS and bring it into Illustrator and pick up the pieces.

I can get it to a pdf file and it is clean.
problem 1 its in 2 and 3 pieces
problem 2 if I try to join them trash I use eps the first time

I have acrobat 5 but can not seem to find a way to merge 3 sheets of paper to make one.

I have photo shop but that messes up the files

I have tried saving as tiffs and then joining but I haven’t seen the results on the ripper and the negitives yet.

I will try illustrator

There is an illustrator plug-in called Concatenation which might help you join-up the disconnected bits from Excel.

I would also suggest that you consider upgrading to Acrobat 6 Pro if you are going to work with PDFs.

This is a one time job right now

pdf are the output needed for the ripper
it takes the pdf and seperates the 4 colors and creates the negitive for the plates.

If the excell work was on one sheet of the workbook then I would just drop into the pdf maker and be done.
(i did this with 2 of the documents)

but because it was on three sheets I am getting 3 pdfs
which I need to join to make one 8.5 x 11 sheet of paper.
