I am looking for a person who works with 1-bit TIF files on EFI colorproof XF. I am print proof raster files, however without color management. How and where should I include profiles: referential, paper one and a file after linearization done by us. I am looking forward to Your help.

Hello,

AFAIK you'll have to own another RIP for producing the Rasterfiles, for example a Harlequin Navigator rip, because the EFI XF can't produce these Rasterfiles on it's own. You can save rasterized files from the rip in tiff format, which means the rip must have already included colormanagment during seperation there, using the profile you want to simulate by EFI XF later on. That is, if you're using In-Rip-Seperation, if you send pre-seperated files (for example from Quark or InDesign) there will be no need to include colormanagment in the rip you use for creating the 1Bit-Files.
You can simply put these seperated tiff-files in your printer-cue in the efi jobexplorer, (presupposed you own the OneBit-Option). You have to set Simulation and Paper profile in your EFI-Workflowsettings, Simulationprofile must be the same profile which you already used for seperating the 1BitFiles with the other rip or software. If you haven't created a colormanagment workflow yet, you'll have to use the Workflowdesigner -module to create one.

Also the OneBit-Option of the EFI-Software won't simulate a very fine raster properly and it's not able to show up common problems of rasterization, such as moirè and so on.

I hope this was helpful of any kind.

Thank you Koder! Due to your reliability ( we’ve read your other opinions) we still count on your help, if possible. The problem appears to be far more complex for us.Our RIP “PSM7” does not generate TIFF files.We generate 1-bit TIFF files in Photoshop where the LPI is satisfactory for us.The print outs we receive on our EPSON Stylus Pro 4000 printer have the correct raster , however the colour still appears to be incompatible with the RIPA Best Colorproof M print outs. We send you link to the print-screens of the particular stages as an attachment. We will be grateful for your quick response and invaluable help

Hello again,

>we’ve read your other opinions

- How???

ok, I'm trying to help out a little. I'm not very experienced in Rasterproofing but maybe I can tell you something about the normal colormanagment-settings of CPXF.

Your Workflow is not configured for colormanagment yet. So go to System-Manager and set the workflow offline by clicking the green dots. Otherwise you won't be able to change settings.
Then go to "Workflow-Designer" and choose "Load Workflow" from the Menu. Load your Workflow (Workflow-Name followed by the word "offline") and click the color symbol.

Now for the settings:
Source-profile:
If you are working with different sourceprofiles leave it NONE, instead check "use embedded if available". This maybe not working with Rasterproofs, that I don't know. If your Proofdata is always in the same CMYK-Colorspace (maybe your custom Working Colorspace in Photoshop) you can set this as the source-profile, but there's no need to, the data is already seperated and won't change.

Destination/Simulation profile:
This should be the Profile of the machine and/or printing circumstances you want to simulate with your proof, for example isocoated.icc if you want to simulate european standard for offset-printing on paper class 1 + 2.

Visual Correction Curve (VCC):
This is more a possibity to "tune up" your proofersettings when you're not completely satisfied with the results or you haven't got a measuring instrument. So leave it unchecked for start.
The standard linearization is not done by Visual Correction Tool, you use the Option "Linearization by measure" (don't know the correct name in english, it's the left option of the colormanager). The linearization won't save a Correction Curve-file, it will overwrite the EPL-file of your paperprofile which CPXF generates by itself (simply when you put a Paperprofile in the Profile-Folder.).

Where to put Paper profile:
Paper Profile must be set for the PRINTER, not the Workflow. Go to System-Manager, choose your Outputdevice and select your Media and Inks. CPXF will load the profile automatically if it's in the right folder and generate a linearization file (epl).

Plate Compensation:
I really don't know anything about this.

Connect Profile:
This option is only needed if you want to connect a Linearization to a specific Paperprofile, to make sure it's only used in combination. But there's no need doing that.

ok, that's it. For more you should consider reading the manual or visit the link loethelm posted. Hope I could help.
P.S: Sollte ich hier irgendetwas falsches geschrieben haben, bitte ich darum, mich zu korrigieren!

Hello Koder!!!!

Endlich haben wir den Erfolg erreicht. Unser RasterProof hat schon des ICC-Profil und ist identisch mit dem Muster bei dem BestColorProof.
Wir mußten nochmals XF installieren, indem wir insbesondere die Papierprofil in Betracht zogen. Dabei erschien, dass wir früher einige Probleme haben.
Wir möchten Dir fűr alle wertvollen Hinweise danken.
Wir wünschen Dir Alles Gutes.
Herziche Grüße!
