Troubleshooting

Opacity problems, such as a light color not covering a dark material.

Print a white undercoat on the material before printing the other colors in the job. Use the
GerberColor Backing and Finish dialog box of GSPPlot to apply the undercoat. To open the
dialog box, click the Backing/Finish button from the Print Options dialog box of GSPPlot.

The top or bottom of a job is consistently darker than the rest.

There may be a print head pressure problem. Please call your distributor or Gerber Service.

Light spots in a repeating pattern in the job.

Clean the platen. See "Cleaning the platen" on page 87. If the problem persists, please call your
distributor or Gerber Service.

Poor print registration.

Do not butt colors in a job. Use traps, bleeds, chokes, and spreads to improve registration as you
design the job in OMEGA. Unroll the material 15 minutes before printing to allow it to
normalize to the environment.

Stretched sprocket holes in the material.

Use only EDGE READY™ materials for the GERBER EDGE FX. Unroll the material before
printing to allow it to normalize. Check that the movable rear sprocket moves freely. If the
problem persists, please call your distributor or Gerber Service.

Printed images lift from the material or material lifts from the liner.

A job printed on material can be sensitive to transfer tape pressure. Wait at least 15 minutes
before applying transfer tape to the printed material. Use only Gerber Standard Tack
Application Tape.
Tip: Do not stack printed material with printed sides together. Stack the printed side
contacting the liner side of another piece of material or use a paper interleaf between the
layers.
