Dirt appears on right side of graphic when imported

[Ruth Shaw]

Photoshop 6 files I have opened in 7.0 and worked on show streaks of gray dirt (or pink if using cmyk!) after the graphic is imported into FrameMaker. The columns of streaks are always on the right hand side of the graphic, and I can hide them by making the canvas size larger on the right and the dirt disappears (or is hidden) beyond the box edge. But why is it appearing at all?!! This has happened everytime I have used Photoshop 7.0 to work on an image previously worked on in 6.0 photoshop. The dirt does not show up in Photoshop, but is easy to see on the screen and in printouts from FrameMaker. Thanks for any help!

What is the image mode (RGB, etc.)? What is the bit depth, and what type of file (gif, etc.) Is it possible that we are looking at posterization or perhaps there is a gamut issue?

[Ruth Shaw]

Tiff files; 8 bits depth; most of the work I do is with scientific graphics and line drawings. I generally use grayscale at 600 dpi for my press work, once in a while bitmap at 1200.

Is it possible to create a JPG and post it on a website somewhere and tell us the link? It's kind of hard to imagine what we're talking about here.

Tony, I am utterly discouraged about the posting - I have a website but I hated the software and seem to have deleted it (I am more of a press person than web you might guess). The light grey streaks show up intermittedly, and generally faintly, as vertical columns (sometimes only a few streaks, sometimes many) on the far right of the graphics. I have a single page pdf I can email anywhere with the faint problem showing. Is this helpful? Thanks, Ruth

Sure Ruth; I'd be happy to take a look but can't say how much help I'll be. My main goal for suggesting a post was so that others would be able to contribute, but I'll give it a shot.

Ruth,

I just looked at the file. Are these scanned images?

If they are scanned, then it's simply a matter of finding them before moving them from app to app and erasing them. I always do a levels command and look at the right hand side of the historgram. If there are some data in that area, I use the slider to remove them.

I can't imagine what they would be if not scanning artifacts, but will wait until you confirm it.

Peace,
Tony

Tony, This problem has shown up in a lot of different types of graphics - none of which were scanned as far as I know. This particular one was sent as a .ps file, which I distilled, opened in photoshop (originally - using 6.0) and replaced text to bring it in line with our styles. Later I opened it in 7.0 for some additional editing and after saving it as a flattened tiff and importing it into Frame the dirt showed up. It DOES seem to happen more with pdfs that are opened in Photoshop (and later saved as tiffs)- even with adjusting brightness to make sure there is no background screen. Ruth

Use the levels command and look at the histogram once they're in Photoshop. That way you can be sure whether or not they are present and correct them with the slider on the right.

They look like they were scanned and that is a scanner (bed) artifact. Even though you didn't scan them perhaps your source did? If the person who created them is creating a postscript file directly from the application, then this is a very odd problem, which I cannot address.

So my point is, I'm betting it's scanned, they are always there, and what you're seeing is a difference in color settings between two photoshop versions sessions - that part is a guess.

When I opened it, I see that it's in Indexed Mode and am not sure if you would have better results in Grayscale or not.

Again though, I'm betting it's a scan artifact and that your images need to be cleaned before placement into Frame.

Peace,
Tony

Thanks, Tony - I will do so, and I appreciate your suggestions. Ruth
