Aqueous Coating

An aqueous coating is a fast-drying, water-based, protective coating which is applied in-line on press to attain a selection of finishes more economical price than varnish. Aqueous coatings are not used in a printing unit, as varnishes are further distinguishing them apart from each other.

Aqueous coatings are applied to a printed sheet right after the inks, in a coating unit. Directly after the coating is applied, the sheets are sent through a heated air system that quickly dries the coating. The printed sheets can progress to the finishing department in a matter of minutes, as opposed to traditional varnishes which may need hours or even days to dry.

This type of coatings provide marvelous rub and scuff resistance. They give protection that far exceeds standard varnishes. It protects the product from harmful elements from the shipment through to end use. They are available in gloss and matte finishes.

We offer satin and gloss aqueous coatings in our sheetfed press department.

Varnish

Varnish is essentially ink without pigment. It requires its own printing unit on a printing press. It can be wet-trapped (printed in-line at the same time other inks are laid down), or dry-trapped (run as an additional pass through the press after the initial ink coating has dried). The latter often provides a glossier finish. Varnish comes in gloss, dull, and satin (in-between dull and gloss), and can be tinted by adding pigment to the varnish.

Flexographic Printing

“Flexo” as it is called, is a print process using water based inks transferred by special rollers onto a raised type printing plate that applies the image directly to uncoated paper. Flexo print units mounted within the envelope folder allow for economical print and fold in a single operation. Time consuming make-ready means flexo is best suited for runs over 200M. Flexo image quality is good for type and line copy. Flexo is not a substitute for offset if precise color match, process build color or coated papers are required.

Flexographic Printing

Flap

There are three types of flaps on an envelope – Side, Bottom and Seal. The Side flaps are the tabs that are folded and gummed to form the envelope pocket. The Bottom flap is the protion of the envelope that folds up and is sealed along the sides edges to the side flaps to form the pocket. The Seal flap is the flap that is folded down and sealed after inserting contents. Seal flaps may have remoistenable, latex or peel and stick adhesive closures. Seal flaps may be square, pointed or tapered. Standard flap styles such as Commercial, Square, Pointed and Wallet are specified depending on the envelope’s intended use. Commercial flaps are designed to be compatible with automatic inserting and sealing machines. Square and Pointed flaps are used in social correspondence, invitations and greeting card envelopes. Wallet flaps’ extended length and over-sized gum pattern are used to seal securely and enclose thick multi-page contents.
