I'm using Corel 9 and an Epson 1200 printer. Since this is a simple job, I'm going to print a good quality proof onto glossy film so that plates can be made straight from it (without the need for a positive). The problem is that there is an area of even grey in my design. Is there a way of forcing the computer to print an even halftone instead of the error diffusion that it uses to print grey? What I want is to force the inkjet printer to print out a grey pattern that might have come from a laser printer. But I want to do this with the printer set at maximum resolution, so that the text comes out very crisp. If not, how do I select a pattern of dots small enough so that it looks like grey? Corel won't let me reduce the available "dots pattern" enough. Thanks in advance Antun

You can't print a conventional halftone from an inkjet printer. At least not any inkjet I've ever seen. I've had the same problem for screen printing since they need real coarse screens, like 45lpi. What I did was export the graphic as an EPS or TIFF and open it in PhotoShop as a Grayscale image. I then converted it to a Black and White, 1 bit TIFF, and chose Halftone Screen from the choices, choosing 45lpi and round on the next prompt. It's a pain in the ass but you gotta do what you gotta do. Mike On Wed, 10 May 2000 18:07:23 +0100, "Antun Karlovac" <arson@base-bam.demon.co.uk> wrote: >I'm using Corel 9 and an Epson 1200 printer.
