I am sorry for my English! :)A problem with printing bitmap. Black contour. There was about 2 weeks ago. The settings are not changed. I have: CorelDraw X8. The printer: Konica Minolta BizHub C220How to fix it? Help please!
I'm assuming that the line astound the horse shoe is the issue, correct?
Is this device a RIP driven device?
Do you send a PDF file to the device or choose file/ print from the menu?
I print through Crt + P. (Menu / Print) "Default" Printing settings in CorelDraw
Sharing this problem across RIP driven devices, laser engravers, and occasionally a laser printer: VERY curious if specific .CDRs can replicate these artifacts in different environments; very curious about the postscript possibility- just conducted the 1,000th test and can say that exporting the flawed .bmp/.png etc to .PDF and importing it back has solved the problem at least once!
Literally had the image, the image resampled (no anti-aliasing, color profiles set to RGB, no interlace, and every other suggestion I've read) and the original line dropping image right next to each other for a job, the one converted to PDF behaved accurately. Since PDF is designed around postscript I am even more suspicious of the postscript and would love to find a way to have it either not handled at all (Corel's print 'direct to printer' or does that still make a stop in PS format?) or else have previews generated in PS so that artifacts like these will show? I've included a .cdr ( I could not upload the file, if I see replies I can try again) that shouldn't run into any legalities wherein my laser engravers and even a laser printer have dropped lines just a few mm above the bounding box of the included .bmps located at the top of the page inside the arching shapes; if anyone can actually identify the PS error, that'd be awesome but in the mean time I imagine we are all handling images as .PDF until Corel can tell us why their images are not compatible with our print drivers... :/
Actually just did a little footwork and have confirmed that the postscript drivers were such a problem they have already been disabled across the board which leaves me scratching my head as to where these lines are coming from and why PDF is getting rid of them...
/and, as of the following day, the file is not replicating the error- possibly fixed moving from X7 to X8 format....
a possible answer is about to align the bitmap to the pixel grid: select the image with the seconday mouse button and choose "object hinting". That should fix the problem
As you can see, I've already lost an actual product to this randomness, very perturbed. Halfway to talking my entire company to learning GIMP, lol. Object hinting seemed promising but after testing did not consistently eliminate the artifact. Interestingly, the artifact changes if the image is flipped- these pixels are definitely Corel's fault, I just can't isolate what exactly is being misinterpreted... after being all over these forums and seeing similar issues nearly resolved throughout X5-X7 I am not hopeful but will be sticking with this if any other trouble shooters want to start sharing notes...
In your CorelDraw print settings, composite tab, Change your document overprints settings from ignore to simulate. This should solve your issue.
Was just about to drop this tidbit here, thank you whoever you are ;P/Those using this fix need to beware that it will duplicate images, possibly based on print page boundaries, in some instances
New Discovery: The simulate document overprints just forces your print as bitmap box to be automatically selected..... so this may not be a complete solution.
