If you increase the vacuum pressure, also increase the tension. The input tension should be the output tension + 15 N/m. i. Try increasing the Vacuum setting by 10 mmH20. ii. Try increasing the Tension settings by 10 N/m. iii. Try increasing the Tension settings by another 10 N/m. iv. Try increasing the Vacuum setting by another 5 mmH20. d. Set the carriage beam to its highest position. 3. If the sample is damp or easily scratched, try these adjustments in this order: a. Check that the ambient temperature is within the optimal range. See Environmental specifications on page 57. b. Increase the curing and drying temperatures, unless you have already decreased them in a previous step. Use the following table as a guide. Curing (°C) Drying (°C) 80 80 85 85 90 90 95 95 100 100 55 60 55 60 55 60 55 60 55 60 c. If all test sample blocks are damp in the 100% to 80% columns, adjust the total ink limit in the RIP. d. If any test sample block is damp in the 70% to 10% columns, increase the number of passes. e. Decrease the ink density, if your current ink density is greater than 100%. To do this, you have to delete the preset you're working on by selecting Substrate > Remove, and recreate it using a different parent substrate. 4. If you see ink bleeding or coalescence, try these adjustments in this order: a. Check that the ambient temperature is within the optimal range. See Environmental specifications on page 57. b. Check that the curing temperature has not been wrongly set. c. Increase the drying temperature in steps of 5 degrees, unless you have already decreased it in a previous step. d. Increase the number of passes. e. Decrease the ink density, if your current ink density is greater than 100%. To do this, you have to delete the preset you're working on by selecting Substrate > Remove, and recreate it using a different parent substrate. 5. If you see vertical banding, try these adjustments in this order: a. Decrease the Vacuum setting in steps of 5 mmH20, unless you have already increased it in a previous step. b. Decrease the drying temperature, unless you have already increased it in a previous step. 32 Chapter 3 Handle the substrate ENWW
