Question 1

What topics does the large format production quiz cover?

Accepted Answer

The quiz covers four core production categories: finishing ROI (lamination, welding, grommeting), RIP and ICC profiling (linearization, ink limits, rendering intents), ink chemistry and curing (latex, eco-solvent, UV), and media mechanics (feed step calibration, head strikes, humidity effects). Each question includes a detailed explanation of why the answer matters on the production floor.

Question 2

What is linearization in large format printing?

Accepted Answer

Linearization is the process of establishing a predictable, linear relationship between the input CMYK percentage values in a file and the actual ink density output on a specific media. It is the first step in RIP calibration and must be completed before building an ICC color profile. Without proper linearization, color profiles produce inconsistent results regardless of how precisely they were built.

Question 3

Why does eco-solvent printing require outgassing before lamination?

Accepted Answer

Eco-solvent inks use liquid solvent carriers that must fully evaporate after printing. If lamination is applied before the solvents have outgassed (typically 24-48 hours), the trapped solvents dissolve the pressure-sensitive adhesive layer, causing silvering, tunneling, and delamination. This is one of the most common and costly finishing errors in large format production.

Question 4

What causes horizontal banding in wide format prints?

Accepted Answer

Horizontal banding in wide format output is almost always caused by incorrect media feed step calibration. When the printer advances the media by a slightly wrong amount between passes, alternating light and dark bands appear perpendicular to the print direction. The fix is to run a step calibration test in the RIP or printer utility and adjust the feed advance rate for that specific media weight and tension setting.

Question 5

What is the difference between latex and eco-solvent ink for wide format printing?

Accepted Answer

Latex inks are water-based and cure entirely inside the printer using heat, leaving a dry polymer film with zero outgassing. Prints can be laminated or shipped immediately after output. Eco-solvent inks use mild solvent carriers that require 24-48 hours of outgassing before lamination. Latex has higher purchase and running costs but eliminates outgassing delays. Eco-solvent has lower entry cost but requires more floor space and scheduling time.

Question 6

How does humidity affect large format media and print quality?

Accepted Answer

Paper, canvas, and banner substrates absorb ambient moisture. High relative humidity causes fibres to swell, changing the physical dimensions of the media and causing cockling (surface warping). Cockling raises the media surface closer to the printhead, increasing head strike risk. It also changes roll media tension, affecting feed step accuracy and causing banding. Most large format production environments target 40-60% relative humidity for consistent output.
