Tips & Techniques: Litho Canvas
1. Acclimatize: Litho Canvas should be acclimated to pressroom conditions for at least 24 hours. If the sheets have been exposed to high temperature/humidity environments (e.g. during transportation) the acclimations period should be extended to at least 48 hours.
2. Make-readys generally must be done on canvas due to the substantial difference in printing properties between paper and canvas.
3. Ink choice is driven by the need to deal with the processing nuances of canvas. The greater amount of ink generally laid down would favor faster drying inks. Some customers uses Kohl and Madden vinyl inks. Others use a variety of standard and UV-curable inks.
4. Higher Blanket Pressure & Softer Blankets are generally used, due to the texture of canvas versus paper. This may impact choices involving tackiness of the ink, amount of ink laid down, and type and amount of anti-offsetting powder.
5. Anti-offsetting Powder is used in increased amounts, as higher sheet weights and greater surface texture combine to make offsetting more of a problem with canvas. Experimenting with different types of powder and using shorter run lifts are also used to combat offsetting.
6. Dusting & Sizing: Canvas will usually have more dust, lint, and other “contaminants” that can cause hickeys or other printing problems.
a) More frequent blanket cleanings will be necessary during the run.
b) Some printers opt to clean the sheets by running them through the press with dry blankets before printing.
c) Some printers apply a size coat front and back to “lock up” any lint or material not removed on the blankets.
7. Caliper Variations are greater with canvas. There can be as much as 1.5mils variation within a sheet and one side of the canvas sheet will generally be about 1mil thicker than the other. As such it is important to always feed the canvas into the printer in the same orientation.
8. Line Count: 150-170 is average, but some printers go up to 200.
