Setting Passes Drying temp. Curing temp. Heating airflow Substrate advance compensation Description If too low If too high The number of passes specifies how many times the printheads will print over the same area of the substrate. The amount of ink fired per time unit is larger and ink has less time to dry on the substrate. This may create coalescence and banding. The boundaries between passes may be more visible. However, printing speed is relatively high. Colors are vivid, print quality is high. However, printing speed is relatively low. A lower curing temperature is needed, otherwise the substrate may be deformed. The heat applied in the printing zone removes water and fixes the image to the substrate. Print-quality defects such as banding, bleeding and coalescence may occur. Thermal marks may be seen on the substrate; they may appear as vertical bands in some colors. The substrate may wrinkle on the platen, causing vertical banding, ink smears or substrate jams. Curing is needed to coalesce the latex, creating a polymeric film which acts as a protective layer, while at the same time removing the remaining co-solvents from the print. Curing is vital to ensure the durability of the printed images. The print may emerge not fully polymerized, so that the ink smears when rubbed. The print may appear wet, after printing or later. You may need to increase the number of passes to achieve adequate curing. The substrate may wrinkle under the curing module, causing defects such as blisters or liner detachment. The substrate wrinkles may also cause vertical banding or ink smears at the beginning of the following plot. Airflow helps to remove the evaporated water from the print zone and thus allows more efficient drying. In general, use the substrate family default value. Your printer was calibrated at the factory to ensure that it advances the substrate accurately when using supported substrates in normal environmental conditions. However, you may find it useful to adjust the substrate advance when printing in an unusual but stable temperature or humidity level, or if the substrate-advance sensor is not working. You may see horizontal banding or grain. You may see horizontal banding or grain. ENWW Add a new substrate 43
