First, print parameters. If the resolution is set too high, the number of passes is too high, or unidirectional printing with full feathering is used, image quality improves but speed drops by half. If you want higher output, the parameters need to be reasonably balanced. When all settings are maxed out, printing speed will definitely slow down.
Second, the printhead and ink system. If there are too few printheads, or if they are aging, clogged, or overlaid with too much white ink, speed will not increase. Daily maintenance must be done properly — when the printheads are in good condition, printing can be fast and stable.
Third, curing and software. If the LED lamp power is insufficient, speed must be reduced to prevent ink from remaining tacky. If the computer has low specs, or the RIP software is not optimized, data transmission may stall, forcing the printhead to wait — and efficiency naturally drops.
Fourth, the environment and consumables. If the temperature is too low, the ink becomes thicker; if the material is uneven, speed must be reduced to ensure print quality. So if you want high output and good quality, every detail needs to be in place.
