NE3104-VC11A Printheads
For Photo Color Printers
(310DPI;dots/inch) NE3104-VC11A
NE3104-VC11 series is newly developed for photo color printers as (color print) thermal printheads, high speed, high quality printing is acheved with several new technologies. Printing method is available for sublimination type of thermal transterence. Application Home printer Photo KIOSK Features 1) 9 tit-angle with near-edge structure to work with larger platen. 2) High quality printing with less unever imaging by employing the glaze of very little undulation. 3) Resistance variance less than 1% in the head using special pulse trimming technologies.
