Monotech systems offers sky jet old master series printer, which can configure up to 48 xaar-128-200 print heads, and their high speed printing capability can reach 100 m2/h/4pass. By using drum roller of 485 mm dia, it can realize 5 meter printing and its linearity process and media feeding ability ensure the reliable printing of 5 meter printing image. By using arc-shaped printing structure, the problem of print head scratched due i to the pleat of media can be avoided. The minimum distance of 1.5-2 mm between print head and media can ensure the 1 highest printing resolution. By using the strong feeding structure of belt-friction, media feeding can realize stable media feeding of printing rolls with dia between 500-1,000 mm, which can ensure that the length error of two 50 meters long pictures is lower than 0.5%, ie, 25 mm. The single roller structure of skyjet old master printer makes the media loading much faster, no need for media traction and is very simple to adjust the media.
