Is possible to print positives films with Epson 7880?

I'd like to print them without using any RIP, because i'll mainly print in spot colours...but when i need to print in halftones and process colors (CMYK) i'd like to use Ghostscript.

I'd like to know anyone that say to me: yes i regulary print films with my Epson 7880 in that way, and works like a charm

Thank you all,
Fabio

You can print film from the 7880 with or without a rip.

The ghostscript settings I use are identical to what can be produced with the epson printer driver. If you don't want to use ghostscript, you don't have to.

How can you say this? Comparing the films printed using the Epson driver and using Ghostscript?

The only "but" is that if you have a poor quality exposure unit, the density of the film may not be dense enough.

It isn't my case, i have a 100x140cm vacuum exposure unit with 9 UV 40W neons

IMHO, it is better to upgrade the exposure setup than to try to darken the film.

What do you mean with exposure setup? Using A RIP instead of don't using it?

A poor exposure setup will still be a poor exposure unit. With my vacuum frame and single point light source i've never had a problem with film produced using the the printers standard driver.

Okay, thanks!

ps. i haven't undestood if you have a Epson 7880 or not

pps. i've PMed you

I can say this because i reverse engineered the code being sent to the epson.

Mhmh..exactly what did you discover?

The 7880 is a great printer, so all you need to worry about is everything else

Thanks!! So i'll buy it!!

Probably the most interesting thing i found what that the color density slider doesn't change the droplet size, but instread deletes pixels from printing. In order to get the epson to print 100% black, the slider must be set all the way to the right.

Oh, this is really a interesting discover! Epson should specify this instead of declaring that the machine check every drop.

Another thing interesting was that the epson does support drip size, but the size of the drop is chosen by the paper. It seems that up to 1440x720 the large droplet size was used, but past that the droplet size was reduces.

????

haven't you said 1 minute ago that the EPSON doesn't change the droplet size?

In a recent post i desribe using gsprint to make film using ghostscript. This program uses the windows interface for printing.

Hopefully with the power of the community, we can figure out a usable set of parameters to use a rip for free.

What do you mean exactly? To develop a new opensource RIP?

The price for commercial rips for the 7880 are OUTRAGEOUS!!!

Yes, as all the prices of all the tools.

Oh yes, i've seen this page! I haven't understood however what RedMon exactly does. I've also read the official page(RedMon - Redirection Port Monitor), but i don't understand this sentence:

Using RedMon you create a redirected printer port. If you connect a Windows printer driver to the redirected printer port, all data sent to the redirected port will be forwarded by RedMon to the standard input of a program.

It seems like if the RedMon puts it between the GhostScript and the input program like Illustrator, and it sents the data received from the input program to Ghostscript, jumping the step of the "Print to file" and open the file with GhostScript, sending it in print.

In a few words it should be possible to print directly from the input program the positives, using the rip.

Is it right?!

Thanks,
