Print Quality
3. Find the vector length accuracy by selecting parallel vectors and/or figure distortion by measuring
the diagonals in the selected area.
4. Note the measurements to access the printer’s performance. It will help to keep the measured vectors
identified by using the name convention marked on the plot i.e. A1, A3. This makes it easier to iden-
tify exactly the areas of the plot where the measurements were taken.
Corrective Action
1. Reload the media following the exact steps from the User’s Manual.
2. In some cases, differences in the media advance along the scan axis could cause geometric defects.
Try adjusting the settings in the RIP. Adjust Vacuum level and Backtension levels. Be careful when
adjusting these settings, refer to the RIP supporting documentation for further details of this type of
adjustment.
3.1 Inks on Substrate Test
The Inks on Substrate Test plot is used to determine the level of performance of the Drying and Curing
Assemblies and to determine if they are performing as expected. To print this test plot go to Menu List>3.
Inks On Substrate Test>3.1 Print Ink Test Plot.
At the beginning of the plot is an area used to stabilize the printing system before the diagnostic print is
printed, this area can be ignored. The diagnostic area of the print contains colored blocks representing
each of the primary and secondary colors, the plot shows a scale from lighter to darker intensity (amount
of ink). The plot is printed with a 10 pass print mode.
NOTE: To check if a printer complies with the technical specifications, please refer to ‘Line
accuracy’ section in the printer’s data sheet.
NOTE: After loading media, allow the media to stabilize before printing the plot. Some types
of media require up to 3 meters before it is stabilized.
