Hi. ok this may sound stupid but give me a break. i have never had to priint my own images onto transparancy film before . i had a buddy who worked at kinkos that did it for free. so i am reading about what i need. i keep hearing the term "rip" which i guess is software that allows you yo print half tones. ok. i am aware of the free download website , but my question is basically how do i know if i need a "rip". i printed out a black and white photo on it and it came out fine looking. does that mean i dont need a rip??? because it did have many different shades of gray. also can someone please explain to me and to whom ever is reading this what a rip is exactly and anything you can tell us about it. leave no detail out or as much as you know.

A normal ink jet printer can not print out half tones in the DPI needed to burn a screen. What the ink jet printer will print is probably 300 or higher dpi. To bur an image into a screen you need somewhere between 20 to 60 dpi. The dots from an ink jet printer will be to small to burn with out a RIP software. The RIP software will allow you to control the size of the dot (dpi). The dpi you will need will depend on the image you are trying to burn and the screen you are trying to burn it on.
Hope this helps.

No, for B&W line art you don't need a RIP but you will get much better results by using a decent RIP. It depends on how much film you use.

RIP Raster Image Processor, converts Vectors or whatever to a separated set of art files with each color as its own bitmap ready to burn screens from, and allows you to adjust your output channels for each color by changing the DPI of the screen values, and also the angles the dots are printed at to prevent moray patterns from occurring. Hope this helps!

If you use a Postscript printer (one that uses the Postscript language rather than a printer specific code) you can specify halftones and trapping, make things negative and print print to separations. Life is so much easier.
I like Wasatch SoftRIP, it's probably the best for screenprinters, (IMHO).
