UV Flatbed Glass Printing: Panel Fit and Bed Loading
Four 1.2 × 1.4 m glass panels fit within the reference print envelope on paper. Check whether the bed can carry the calculated 100.8 kg.
This application example uses public references and explicitly stated planning inputs. Figures derived from assumptions are estimates for evaluation, not measured customer results.
Production question
Can four 1.2 × 1.4 m glass panels fit a published 2.5 × 3.1 m print envelope?
Worked calculation
In a 2 × 2 grid with a 20 mm internal gap, the footprint is 2.42 × 2.82 m, leaving 80 mm across the width and 280 mm in length before fixtures. At 6 mm thickness and 2,500 kg/m³ float-glass density, each panel weighs 25.2 kg and four weigh 100.8 kg.
How to validate it on the shop floor
Confirm total bed load, allowable point loading, usable registration zones and clearance for clamps on the actual printer. Validate edge-to-edge placement and ink coverage with a dry run before loading glass.
What to do with the result
With the grid centered, the theoretical edge margins are 40 mm on each side and 140 mm at each end. Subtract any exclusion zones before calling the pattern usable. Loading four sheets may require different handling and registration from printing one large sheet, even when the artwork fits. Confirm the manufacturer’s loading instructions and run a non-printing traverse at the intended head height with the fixtures in place.
Practical follow-up
Does a 2.5 × 3.1 m print specification also prove that the bed can carry 100.8 kg? Confirm load rating and loading method separately. The calculation uses a public reference model as a dimensional example.
When sizing a large format UV printer for glass, check the registration and fixture exclusion zones as well as the usable print envelope.
