1. make EPL file
2. print chart from preview or from adobe print utility, not from efi
3. measure normally in Profiler
4. Generate ICC profile
take care that printer driver have sRGB PCS (read, small gamut)
hmmm you are wrong. RGB and CMYK are color spaces. You talk about RGB devices and CMYK devicesOriginally Posted by djah
truth is that sRGB monitor have smaller gamut than CMYK printing press.
Printer color gamut is question of printing media and ink you use
If you choose input profile ECI RGB or Adobe RGB EFI will simulate input profile as much as output (paper) profile allow.
i could not say what is better. RGB or CMYK workflow. in both case when i compare printout with ref. data everything is fine.
maybe with Fogra LAB wedge ( which i don't have) i would measure/say different things
till than, i/you will guess
sRGB is not a PCS (profile connection space) & has not ever been a PCS nor will it ever be a PCS. It is just a simple ICC profile, which itself uses a PCS but it cannot be a PCS. Don't know exactly what you meant there.
EPL = Efi Printer Linearisation
Prelinearistion give best result, but you can work without.
That is exactly what we needthen the entire profile could also be made inside XF/Color Manager. Also, if one were to print the profile target from the Adobe Print Utility as you suggest, they would then not be making a profile for their printer/XF, because XF was not used to print the target.
print without EPL, without linearisation, because when we print from photoshop, we can't use it EPL file
thats exactly what we do! Purpose of Efi color manager is to acquire data and to generate icc profileFor the profile to be accurate, it has to be made using the exact same print procedure as what will be used for final printed output.
PCS - profile connection space is link between input and output, "a translation between two color spaces can go through a profile connection space" - citationsRGB is not a PCS (profile connection space) & has not ever been a PCS nor will it ever be a PCS. It is just a simple ICC profile, which itself uses a PCS but it cannot be a PCS. Don't know exactly what you meant there.
ICC describe that PCS could be CIE lab or CIE XYZ. in that way every human visible color can be described. Vendors like Heidelberg, EFI, Xrite use CIE Lab or CIE XYZ as pcs.
sRGB is color space
sRGB icc profile describe sRGB color space. Everything (from input) is converted inside printer driver to sRGB and after that converted to Printer/media color space. In that way sRGB is PCS
you can find article on internet what is sRGB
but, because sRGB can't describe every visible color, printing without high end rip, using plain printer driver,
your print output is limited with sRGB color space
There is another interesting way. With the help of a composite PDF Flexoperfection with rasterized separation. It and print it. Colour accuracy is within reason, and batch processing to automate the process.
EFI Colorproof/Fiery v4.5 CAN generate true RGB ICC profiles. These "Media Sets" can also be used in EFI's eXpress Photo application.
An even easier way is to simply do whatever needs to be done in Ps and then just save the TIFF and take that TIFF directly into EFI and print from there.
can efi express be calibrated in the same way?
a) use standard epl or to create the custom one with EFI XF;
b) create RGB icc profile with the third party software - i1P, ProfileMaker, Monaco, ArgyllCMS etc.
c) Connect a to b in ProfileConnector to create media set.
What are people using to print Photography prints? I have an epson 9800 with an efi rip. I have only gotten good results if I convert photos to CMYK first. Are there any products that will take raw images from a camera and proof out the photos without converting them?
Any suggestions would be appreciated.
Anybody knows if EFI will help me with epson 7880C textile ink to get beter results with colors ?
