Paper / board application route
Application
Ink and varnish matching for paper bags, folding cartons, printed sheets, paperboard, and suitable volume-driven corrugated box enquiries.
Application fit
Begin with material, print process, handling requirement, and the issue that needs checking. Application pages are not a guarantee that every substrate, structure, or end use is already approved.
JLJ Coating can discuss water-based ink and varnish options for this application when the buyer provides substrate details, printing process, current issue, and target property. The most useful sample conversations include real substrate or printed samples.
Buyer short answer
Paper and board are not one uniform substrate. Start with the actual material, printing route, color or finish target, and downstream handling before choosing an ink or varnish direction.
Share the paper or liner grade, printed side, absorbency or coating, anilox, line speed, dryer setup, target color, and rub requirement. Corrugated remains within this paper-and-board route and is best discussed for suitable volume-driven enquiries, not as a universal-fit claim.
Use WOP for the published transparent, smooth, gloss direction, A0126 for a uniform matte surface intended for subsequent printing, and model 24-10-33 for tactile soft touch. Another target requires its own identified grade. The actual substrate, coating process, drying, downstream printing or handling, and sample result remain part of every trial.
Use color-matching support when a new target must be developed. Use the weak-print diagnostic guide when an approved target already exists but the press result is pale, patchy, or loses strength during the run.

Final technical properties should be requested for the selected product and trial condition.
Buyer path
Use the product route for ink selection, the color route for a new target, and the diagnostic route for an existing print that scuffs or fails a defined rub check.

FAQ
The catalogue-supported route is water-based flexo ink for kraft paper, white card, coated paper, corrugated board, paper bags, and related paper packaging. Selection should still be matched to the exact material surface, flexo setup, color target, drying setup, and trial result.
WOP can be evaluated for a transparent inline gloss finish, A0126 for a uniform matte surface intended for subsequent printing, and model 24-10-33 for tactile soft touch. A separate resistance target needs its own exact grade and evidence. Final performance depends on the full ink, coating, substrate, and process setup.
Send substrate type, printed sample if available, target finish, press process, drying condition, and the main problem you want to analyze. If A0126 is being evaluated, also identify the intended subsequent printing process and ink.
A clear inquiry should include substrate type, print method, current ink or varnish issue, performance target, and any downstream converting requirement.
