Hi there,

maybe some one got a better picture of what EPSON has thought on the SpectroProofer device for the 7900/9900 series in terms of linearizations...

We have used the Z2100 for quite some time – the linearization process is dead easy. Use either the control panel at the printer or the application ColorCenter to perform a linearization that is saved within the printer and implemented for everyone that uses the printer.

With the 7900/9900 I'm totally confused. It's for sure that there is no option to linearize the printer from the control panel (which would be the preferred option) – instead I have to use an application call SpectroProofer Utilities. It run – at least to some extend (not being able to work on NON-EPSON media and 1 of 4 resolutions for a specific media crashes the app are just the first issues that I ran into) – BUT... where are the linearizations saved to?!? As far as I figured out the linearazation is saved locally and not on the printer...

The online help is quite so-la-la on this. It reads like "the calibration data will be saved for every media and will be implemented in the printer driver". NOT GOOD. What makes things even wors is another little line found there "calibrations are available for other users using the shared printer" – ooops does EPSON really use an host based approach for linearization? Hope I'm wrong...

If anyone has some more info on this – maybe even a whitepaper or so – would be appreciated very much!

Bye,

Lorenz

The bottom line is, if you don't need to create certified proofs (with deltaE reports), you don't need the Spectrophotometer for the newer 900 series. You could get a standalone package (like an EyeOne Pro) to build custom profiles for far less and do more with it. IOW, its really designed for the proofing market, not the photo market.

Hi Andrew,

well that's what the 9900 ist just all about at our site – proofing. OkOk – 95% of the time. I know this forum is quite photo-biased – but the knoiwledge of the people around here is WOW...

Therefore I simply hope that someone might jumpf into who simply understands the SpectroProofer approch better than I do :-)

I suggest you take another look at the tool. You can import and export lin files.

hi doombrain,

thanks for your reply – well that works – BUT...

think like this: you have 20 clients. you generate the linearization on 1 machine. save it. import it on e.g. 17 clients – but forget about importing/installing it on the remaining 2 machines. not too funny when you rely on tolerances. and then the one of the 17 users updated the linearization on his/her machine but not the others.

nono – the way HP has implemented it (centrally on the printer itself) is just too simply.

i stil hope that I missunderstood the whole thing – BUT i talked to epsons tech support today and it really seema that they assume that all users will print with "normal" printer drivers via ONE hoste that does all the linearzations for the whole workgroup... :-(((

bye,

Hi everyone...

had a lengthy and very professional talk with an EPSON tech supporter for the Stylus Pro series...

The linearization issue is very simple: there is NO linearazition thru "SpectroProofer Utilities" on the printer itself – all linearizations are saved locally on the host (Windows or Mac) and applied when printing thru the EPSON printer driver.

This means also – if you use any kind of RIP that does not use the EPSON printer driving (usually the don't) the linearization preformed by the "SpectroProofer Utilities" will not have any influence on the print out.

Well – the approach doesn't make any sense for me – but you mileage my vary.

Case closed.

Bye,

Lorenz
