Rotary Screen Engraving Machine 720DPI Inkjet CTS Engraver for Textile Screen Making Industry

For a large rotary screen printing mill, the screen-making workshop quietly controls three numbers that decide profitability: screen cost per design, changeover lead time, and first-time acceptance rate. The DOSUN Rotary Screen Engraving Machine is a computer-to-screen (CTS) inkjet engraving system purpose-built for mills that operate multiple rotary screen printing lines and need a dependable, filmless screen-making capacity of their own. The machine prints the design directly onto a coated nickel screen with dedicated engraving ink and fixes the image with integrated UV curing, so screens are ready for the printing line without film masters, darkroom exposure or manual registration steps.

Most Indian textile mills still feel the daily pressure of conventional screen making. This machine was designed to remove each of those pressures at the source:

• Film and chemical cost: film masters, darkroom consumables and wet processing add cost to every single design change. CTS inkjet engraving eliminates film completely and cuts chemical handling to a minimum.
• Head-end joint defects: manual film wrapping often leaves an open or overlapping joint that ruins printing quality. Digital printing with engineered joint control produces a seamless connection every time.
• Slow design changeover: waiting hours for exposure and washing means missed quick-response orders. A new design can be loaded from the computer and engraved within minutes.
• Dependence on skilled craftsmen: inconsistent manual work and shortage of experienced screen makers is a common bottleneck. Software-driven engraving keeps quality identical on every shift and every operator.
• Compliance pressure: export-oriented mills face stricter environmental and brand audit requirements. The filmless, low-chemical workflow supports cleaner production audits and reduces effluent load.
• Reject and rework waste: registration errors and uneven dot quality create expensive rework. Fixed digital imaging holds repeatable accuracy screen after screen.

• Filmless computer-to-screen workflow: designs go straight from the RIP workstation to the coated nickel screen, removing film, darkroom and manual alignment from the process.
• Industrial high-speed inkjet printhead: the printhead integrates 7 groups of nozzles with 96 nozzles per group, delivering dense, uniform ink lay-down across the full screen breadth.
• Selectable 360/720 DPI imaging: switch between production speed and maximum detail, with sharp dot edges for fine lines, half-tones and heavy blotch coverage.
• Engineered seamless head-end joint: the system controls the joint zone digitally so the engraved pattern closes perfectly around the screen circumference.
• Static balanced ink supply: a stabilised ink delivery system prevents starvation and pressure fluctuation during long runs, protecting uniformity from the first metre to the last.
• Wide repeat and breadth coverage: supports screen repeats of 641 mm, 820 mm, 914 mm and 1018 mm with working breadth options of 2200 mm, 3200 mm and 3600 mm, and custom sizes on request.
• Integrated UV curing: the printed image is cured inline, so screens are robust enough for the wash-out and printing stages immediately after engraving.
• Self-developed control software: an easy-to-learn interface developed by DOSUN reduces operator training time and removes dependence on third-party software licences.

Compared with traditional film-based engraving, the DOSUN CTS inkjet engraver removes a whole layer of consumables, labour and process variability, and it pays back quickly through film savings alone. Compared with imported UV laser CTS engravers, it delivers the same digital, filmless workflow at a significantly lower initial investment, with lower cost of ownership for maintenance and spare parts. Mills that later move into laser engraving can stay with the same DOSUN workflow philosophy, since the company has supplied UV laser engraving technology since 2005 and keeps one unified software experience across both technology lines.

The machine is engineered for rotary screen printing mills producing fashion fabrics, home textiles, sarees and dress materials, and for central screen-making units that supply multiple printing lines. It engraves directly on coated nickel rotary screens used with mainstream rotary screen printing machines, making it a straight upgrade for mills in Gujarat, Mumbai, Tirupur and other Indian textile clusters that want to bring screen making in-house with digital speed. The same platform also serves mills in South Asia, Southeast Asia, the Middle East and Africa that run high-volume rotary screen production.

Every machine is fully assembled, calibrated and test-engraved in the DOSUN factory before shipment, and delivered in export-grade wooden case packaging with a complete spare parts kit and documentation. Standard delivery time is 15 days. DOSUN has supplied engraving technology since 2005, backed by a mature service team in China and local agent support in key markets, so spare parts, training and remote troubleshooting stay within reach after installation. Payment terms of T/T, L/C and Western Union are accepted, with a minimum order quantity of one set.
