Q: Who manufactures the Truepress and what is their background?
A: The Truepress is manufactured by SCREEN, a Japanese company with 75 years of experience in the graphic arts industry. SCREEN is known for producing high-quality, reliable printing equipment for various markets, including books, newspapers, and packaging.
How the Truepress Works
Q: How is paper fed into the Truepress machine?
A: A reel of paper is fed directly into the machine from the rear and is then automatically pulled through to the printing unit.
Q: How does the printing process work?
A: As the paper moves, the print heads disperse ink directly onto the sheet precisely where it's needed for the artwork.
Q: What happens if a job is double-sided?
A: If the sheet is double-sided, it's automatically flipped over and sent through a second print unit where the same printing process is applied.
Q: How is the printed paper dried?
A: After printing, the sheet moves to the drying unit. Truepress A uses a heater drum, air, and NIR lamps, while Truepress B uses only a heater drum and air.
Q: What happens to the paper once it's dry?
A: Once dried, the paper is rolled back onto another reel, ready to be moved to the Hunkeler or Muller Martini for finishing.
Commercial Aspects of the Truepress
Q: What quality control features does the Truepress have?
A: The Truepress includes a built-in quality control scanner. This feature checks the output from the inkjet heads (which can be sensitive to changes across many nozzles), leading to less waste and more uptime.
Q: What is the print resolution of the Truepress?
A: The Truepress produces a 1200dpi (dots per inch) true resolution and offers precise droplet control.
Q: How does the costing model benefit customers?
A: This machine uses an ink-based costing model rather than a sheet-based model, which helps to bring down costs for customers.
Pros and Products of the Truepress
Q: What are the main advantages (Pros) of using the Truepress?
A:
Cost-effective to run: It uses high-viscosity, water-based pigment ink, which minimizes ink usage and costs.
Quick turnaround: Minimal setup is required, making for fast job changes (e.g., changing reels).
High efficiency: It requires little intervention from operators, increasing overall efficiency and uptime. Operators can even work on other tasks, like cutting down work on the Hunkeler, while the Truepress is running.
Q: What types of products are best suited for the Truepress?
A: Due to its continuous feed of the same stock and capabilities for longer runs, the Truepress is ideal for:
Stitched Books
Wiro Products
Letterheads
Documents/Forms
The continuous feed ensures collation is maintained, which simplifies finishing and boosts efficiency.
