Re: Margulis "Professional Photoshop, Fifth Edition"
Andrew, The question katheo asked was about a print 5 x 8 inches - Is how one performs output sharpening a critical part of preparing images 5 x 8 inches for printing? I sharpen in RAW processing to correct for the loss of acuity due to digitization. I print in LR due to its ease of use, over Photoshop, and use the output… -

Its not a problem in 16-bit but the conversions are still not lossless. In fact any alteration of original data in any color model results in data loss due to rounding errors (and there are no Lab or CMYK capture devices). Every time a conversion to LAB is produced, the rounding errors and severe gamut mismatch between the… -
Re: Margulis "Professional Photoshop, Fifth Edition"
I don’t know if Dan’s ever used an ink jet printer like you refer to. He’s a press guy. You absolutely do not want to send CMYK to such a device. Give it a try. Also, do you have any idea of the color gamut of such a device and how much of it you are throwing away, along with a lot of other data, to convert to CMYK? CMYK…
