<strong>Verification</strong><br />
<strong>Verification</strong> lets you find out how well the proof is simulating a certain reference,<br />
by printing a verification strip along with the job.<br />
This is an OPTION in the pricebook<br />
How to?<br />
Enable verification in the “Proof (FlexProof)” task<br />
- only for “E-printer” configurations<br />
- Do not use image downloader queues

3. Verify the output – Start <strong>Esko</strong>Artwork <strong>Verification</strong><br />
a. use the <strong>Esko</strong>Artwork <strong>Verification</strong> icon in the <strong>Esko</strong>Artwork Proof Client<br />
Note: by default only 1 license is available for the client<br />
b. use the <strong>Esko</strong>Artwork <strong>Verification</strong> shortcut on the desktop<br />
Note: there are unlimited licenses for the <strong>Esko</strong>Artwork <strong>Verification</strong> application<br />
4. Double click the job in the “Joblist/Preview” tab to load the reference data<br />
Note: The spectrophotometer type and strip layout is detected when double clicking the job!

Hover over the resulting delta E to see the<br />
patch in the color space.

reference = it8 / txt / csv / icc / jdf<br />
Note: reference value: -> must be spectral/XYZ measurement data!<br />
Use cases:<br />
● Strip to strip comparison<br />
● standard references – it8 (FograXX, Gracol, Swop)<br />
