when i take bw laser print from corel draw, the output is not pure black. As suggested in this forum, I tried using the the 'Preserve Pure Black' setting in corel draw. But it turns out to have some adverse effect while converting image from one format to the other (like rgb to cmyk) bitmaps, the black shade on the image looked washed out in multicolor offset print.
what should i do now to get pure black output from bw laser printer without using the preserve pure black setting.
printer : hp 1020
operating system : windows 7
corel draw version : x5

Go to my web site and the downloads link, http://www.graphictechnology.com/downloads.html and get the custom color palettes download. Here there are two palettes, one is a custom cut for the Roland printer the other is a gray scale palette to use in this situation. Use it in place of the cmyk palette for black for black and the problem is solved.
You simplest solution is to go to www.graphictechnology.com and download the grayscale palette I created for use in non-postscript work flows, load it use it. Use that palette for black on all vectors it is in 5% increments up to 100% and is a very close match for the K of CMYK. This will work even for print press work however for ink jet work and digital press the black will have a CMY element added to it. You can let that damn preserve pure black check box unchecked forever as it is a very poor solution to this issue.
Are there also colour objects on the same page?
If not, then you should be able to set the print driver to monochrome -- which will not only guarantee you get neutral greys and blacks, it will also save you money. A typical laser printer costs several times more to print a colour page than a mono page.
