Brief introduction

DOSUN fla inkjet engraver is a digital equipment of CTS (computer-to-screen) for textile print. Comparing with traditional CTF (computer-to-file) technique, it is lower in cost, faster in speed and finer in quality. It can works at visible environment.

 

 As the technology of inkjet print advanced, the inkjet engraver has became the main way of CTS in textile print.

 

With high precision servo system and errors compensation technology, there are no errors in repeat head-to-end joint;

 

With OSUN static ink-supply system, the engraver system almost be non-maintenance;

 

The reducer from Germany high precision, full-closed and good lubricated;

 

DOSUN engraving software integrated rich experience of textile print, and easy to operate.

 

The equipment adopts high-tech components, including the longevity piezoelectricity printhead units, which increase the printing speed and improve the production efficiency. Inside the printhead, tiny spray units shoot ink from the cartridges onto the screen to form characters or graphics.

Software  

DOSUN Engraving software, runs in the machine, is designed by our company ,  all copyrights we own.

DOSUN Engraving software is easy to use. The below figure is a show when the machine prints an image.

l The program can read and print image file format BMP /TIF with 360DPI or 720DPI.

 

l The program offers enough tools of image processing, such as cross mark, screen trim line, image rotation, positive/negative image exchange, image/screen breadth measurement and so on.

 

l The parameters relevant to engraving is easy to set.

 

l The program is green, it do not deal with windows system.

 

l The program runs in windows XP. At least harddisk:80G、RAM:128M、

 

   CPU: P4 1.7G.       

 

l Chinese version and English version could be offered according to user.

 

Characteristics

 

Comparing with other ink-jet engraver been used in china, DOSUN engraver has following advanced characteristics:

 

l Using high speed print head, DOSUN engraver works 20% faster than other engravers.

 

l The print head in DOSUN engraver is provided with seven independent nozzle groups, three of them in use and four in spare when the machine runs .if the nozzle in use clogged ,the spare nozzle will come to run .it enable the print head to work longer .

 

l DOSUN static ink-supply system is almost exempt from maintenance, and provides a stable ink input-pressure for print head.  So DOSUN engraver is more convenient in operation and higher in quality of image.

 

l The reducer made in Germany is high precision, full-closed and good lubricated. Combined with servo motor, It provides exact screen rotary motion. So the image on screen almost has no errors at the step-by-step joints and the head-and-end joint.

 

Work Condition:

 

l Temperature: 20~30°C               

 

l Humidity: 55~80 %

 

l Light :  Yellow light
