I use an Epson Stylus Photo 960 and wanted to know if I should be using RIP software and what type to use? Is there a good resource whether it be book or web to learn about using this type of software with printers?

I have had good results with the Epson Postscript RIP ( <http://www.epson.com/cgi-bin/Store/ProductQuickSpec.jsp?BV_UseBVCookie=yes&oid=1567225&category=Software> ) for printing from Quark, which doesn't like Windows non-Postscript printers.


It isn't necessary for printing from Photoshop, though. All you really need are the right profiles, and proper color-correction.

A RIP is nothing else but a high quality printer driver:

a) can read many file formats, especially PostScript PS,EPS,PDF.
b) can handle large paper sizes.
c) can handle large file sizes.
d) works fast e) is fully color managed. Accepts therefore any RGB and CMYK input profile. Accepts the CMYK output profile for the specific printer.
f) Supports some common printers, especially large format inkjets.
g) Can eventually tile.

This "definition" is based on the features of well-known RIPs like Onyx PosterShop Pro and Best Colorproof.
Of course one may call any driver a RIP, even if not all features are available.

I use Amiable's Photo Print RIP for my large format prints for my HP 2500ps and 800ps printer. As some have mentioned here that RIP's are not for photo's. RIP stands for raster image processor. Isn't a raster image a photo?

Bob,

the gamut of inkjet Mutoh 6100 is as large as Adobe RGB(98).
(you said that CMYK gamuts are smaller than RGB gamuts, this cannot be generalized. Offset gamuts are partly larger than RGB gamuts as well - and partly smaller).
<http://www.fho-emden.de/~hoffmann/gamuts08072002.pdf>

A calibrated CMYK printer is not an "RGB device".

The printer is calibrated for CieLab inputs. The profile contains CieLab--CMYK tables in both directions.

For CMYK inputs it depends whether a source CMYK profile is given (proofing) or not (CMYK values unchanged).
For RGB inputs the profile RGB--CieLab in both directions for the respective RGB space are used.

In this fully color managed workflow by a quality RIP one would send images as RGB and vector graphics (including text) as CMYK to the printer.
