Surface note
The published dry-film direction is transparent, smooth, and glossy; the exact appearance depends on coating weight, substrate, underlying ink, drying, and downstream handling.

Product
Water-Based Overprint Varnish
WOP is an acrylic water-based inline overprint-varnish family for a transparent, smooth, gloss finish on printed paper and paperboard packaging, with the exact stock, ink, coating delivery, and drying confirmed by trial.
Overview
How buyers evaluate Water-Based Overprint Varnish
Start with substrate, print process, target property, current press issue, and trial method before treating any product direction as final.
Water-Based Overprint Varnish is positioned for packaging printers and converters who need a water-based direction that can be discussed technically instead of sold with broad claims. JLJ Coating can review the use case and help prepare a sample-matching path.
Regulated-use, safety, VOC, or similar compliance claims should only be used when written documents are provided and verified for the exact product and intended application.
Matching
Information that should be checked before a trial
These notes keep the technical conversation grounded. They are not universal specifications.
Surface note
The published WOP inline reference is an acrylic water-based overprint varnish for printed paper and paperboard packaging such as color boxes, paper bags, and labels.
Surface note
A matte surface intended for subsequent printing belongs to the A0126 route, while tactile soft touch belongs to model 24-10-33; neither direction should be inferred from WOP values.
Surface note
For boxes, paper bags, and paper labels, blocking and stacking behavior should be checked during trial.

Surface-job comparison
Need matte print receptivity or tactile soft touch instead?
A0126 is the separate matte, subsequent-print-receptive route. Model 24-10-33 is the separate tactile soft-touch route.
A0126 Water-Based Matte Print-Receptive Varnish
A0126 for a uniform matte, subsequent-print-receptive surface on paper, treated film, pearlized film, or a verified synthetic material.
Water-Based Soft-Touch Varnish for Paper and Treated Film
24-10-33 tactile water-based varnish for sample-led soft-touch and matte-finish trials on paper, board, and treated film.

FAQ
Water-Based Overprint Varnish questions buyers usually ask
Is the published WOP reference a gloss or matte varnish?
The catalogue describes WOP as an inline overprint varnish with a transparent, smooth, glossy dry-film direction. A matte surface intended for subsequent printing belongs to A0126, while tactile soft touch belongs to model 24-10-33. Each route requires its own sample approval, and WOP control values must not be transferred to either product.
Can WOP values be used for a water-resistant varnish?
No. Water-resistant varnish is a separate product direction. It requires an exact grade, an agreed test method, the real printed substrate, and end-use validation; it must not be described as waterproof.
Can varnish help improve rub resistance?
It can be part of the evaluation. The team can assist with varnish selection and trial feedback, but final rub resistance depends on ink, substrate, drying, coating weight, and handling.
