I use GIMP to edit PDF files, so that I can rearrange miniatures sets to print more minis per page (printing is expensive here) or putting extra large contour on the minis. But sometimes this happens, the mini gets these horizontal subdued lines, mostly in One-monk PDFs, rarely with others. Sometimes the number of lines varies with the DPI resolution of the importing, sometimes at a determines resolution there isn't any lines, sometimes they are fixed. Any toughs on what causes this, or how to avoid /work with it? Click the image to see what I'm talking about. Attachments:

I have sometimes seen lines like those when I print from GIMP. I always thought it was my printer but now you have got me wondering.

If you click in the actual PDF in Reader, the file, it may (it does for me at least) highlight horizontal lines. I think that's what you're seeing when you import it. I always assumed this was something Jim did in his design process.
You might be able to do a screencap, the Snapshot function in Reader, to capture an image you can then paste into GIMP. Be careful with zoom, because Snapshot will copy what you're looking at, not the native size of the image.

Another thing, I use Linux, when I use Evince (the linux document viewer) it shows the white lines, when I use Adobe Reader for Linux there aren't white lines.
I prefer to use Evince, since Adobe Reader is a bloated piece of... software.
Maybe I can print the original file in the Adobe Reader using the PDF printer and then read the resulting PDF file. I'll get back to you on that.

Tried that. Results where NOT satisfactory. Left side, print to PDF in Adobe Reader, then imported in the GIMP. Right side, exported in PostScript in Adobe Reader, then imported in the GIMP. Attachments:

If you want to use the screen cap function in Adobe Reader, go into the preferences and look for a setting for the DPI of screen grabs. It defaults to 72 DPI, but you can set it to anything. I generally set it to 300 DPI for anything requiring quality. Attachments:

dwargon- Nice, thanks for pointing that out, it'll come in handy.

Try adding a 1px Gaussian blur, that might get rid of the the lines. But then again I have never used gimp so don't know if it has such a function.

Gaussian blur still leaves the lines, although blurred, but very perceptible. The Despeckle filter (with Radius 1; Black Level -1; White Level 256) was the best filter to get rid of the lines, at the cost of loss in the smaller details. But it seems that there is a right resolution for importing the PDF, at which the lines don't appear or are at least very rare and can be dealt by hand. Typically at 300 DPI. Attachments:

The problem comes (i think) from how the OneMonk PDFs were generated.
Basically, they're built by bitmaps arranged as "stripes", and you see them. It was the PDF "printer" he adopted, or at least one of its setting.
I tried some year ago to import that minis as images and i recall that i needed to run a process using Acrobat (not reader) from where i work to have them "reattached" as a whole image.
If the "masters" (the sources) are still available, i'd recommend to Sanity Studios to re-do the PDF in a better way.

I've been going through all the sets and exporting from the source Canvas files to 300dpi Photoshop files. I then do the layout in InDesign and create the final PDF. The re-issued sets are not only created using first-party tools (Adobe created the PDF standard) but are also twice the resolution quality. Try the new sets and see if you are still getting the white lines. You can get two of the free sets from RPGNow. This is why all the old One Monk sets are not yet available. There's much to do.

Yes, the Sanity Studios One Monk files doesn't have this problem. Well done! Old One Monk PDF on the left, Sanity studios on the right: Attachments:

This whole discussion points out my woeful lack of knowledge on the use of Reader. References to Snapshot are beyond me. I don't see how to access that function, even though in General Preferences it mentions Snapshot.
How do you access this function? I currently am needing to build an aircraft (AC130 Hercules gunship) for a friend whose late husband flew one in Vietnam. I found a model from the New Zealand Air Force that I think I can build, but I need to lose the NZ markings and replace with markings from a photo of his plane. This could be very handy.

I've seen it in different places in different versions. In the current one I have open right now, it's under Edit, "Take a Snapshot". When you highlight an area with the selector, it will "flash" and copy that selection to the clipboard.

Aha! On mine it is under Select & Zoom under Tools.
Bless you and yours to a thousand generations!
Thanks

Seems like an important and worthy project VK. Good luck with it.

i sometimes get this problem when printing buildings. I though it was caused by ink levels in the printer. I use a Canon 5150 printer
