Hi. New to forums. Does anyone print halftones on an Epson 1160 without a RIP? Im using Corel X3.
Cheers, Steve

Yes you can but it will be easier and better with a RIP. Try downloading Ghostscript.

As Dave said, yes you can do print halftones without a RIP and generally RIP does makes operation much easier.

It will be a tedious process doing it in corel but if you really want to learn how it can be done, then follow these instruction:

1. Import your picture in corel (Ctrl + I).
2. Resize the image to your size preference.
3. Change the image into greyscale. >Bitmaps>Mode>Greyscale...
4. Change the image's resolution atleast 300dpi (higher will be best). >Bitmaps >Resample...
5. (only do this if necessary) Experiment and eliminate some greys and add highlights to your image by using the tone curves. >Effects >Adjust >Tone Curve...
6. Apply halftone to your image. >Bitmaps >Mode > Black and White (1 bit)...
>>> Conversion Method : Halftone
>>> Screen Type : Round
>>> Degrees : 45
>>> lines per inch (LPI): 40 (lower value will generate coarse pattern and higher value will generate finer dot pattern).
7. Print directly to printer.

Hope this helps, Goodluck!

Which is why printing to postscript and opening in Ghostview is a lot easier and will give you better quality halftones.

I think the halftones coming out of photoshop are basically equal to GS.

Well, I am just fair in use with corel. I do much of the works in PS, and not with RIPs. Takes alot of tweaks though but its worthwhile.

Thanks All, appreciate the info. I know nothing about Ghostscript, I'll look into it. I've printed half tones before using a large postscript printer but was under the impression that the Epson wasn't a postscript printer and I'd need a RIP or something. Printer should be here in a couple of days and I'll hopefully be less confused when I give it a go.
Thanks again, Steve.

PS halftones at (in your case 300dpi), GS will halftone at the resolution of the printer ~1440/2880. They will be better shapes and have more greyscales.
