Quality Control (QC) target job (NOTE: this is an example)
●
Visually check the QC target job and measure the parameters of the QC target job.
●
Save the Daily QC job printed sample as a reference to track past color performance, and
troubleshoot problems in the Pre-Press or within the HP Indigo Digital Press.
Color profiling and refinement (PSP)
Define the color strategy and color profiling for the relevant ink set and finishing type. Perform a rapid
fine-tuning using DFE and on-press color matching tools.
Process preparations in DFE
●
Define the Ink set — CMYKOV covers the best possible gamut when White is in use.
●
Define new substrate with appropriate parameters.
●
Define LUT (Look-Up Table) for charts and jobs (see
LUTs (Look-Up Tables)
on page
39
:
–
For high color accuracy best practices, this procedure will use the default
Linear LUT
on-press
only.
–
Change Default LUT on Press (and in individual job properties) to
Linear LUT
to avoid potential
conflicts with strategy use (Default Job Properties).
●
Define the Line Screen — HDI 175 LPI (see
Line Screens
on page
39
).
