Welcome to our #OKalphabetseries where we visit paper and printing terms daily. Come back each day as we weave our way through the alphabet and share our 110 years of knowledge with you.

W is Wet Strength
Wet Strength is imparted into paper using synthetic resins during paper manufacturing. It allows paper to be exposed to extremes of moisture and water. Paper is classified with "wet strength" if its ratio of wet to dry strength is 15% or more. You may need a paper with wet strength in applications like a wine label or placemat. These durable sheets are a great solution for menus, instruction manuals, i.d. cards and wall charts.

V is Varnish
Varnish is available in gloss, satin and dull finishes. It is essentially ink without pigment. This allows it to utilize a regular ink unit on a press. Varnish can be run inline or drytrapped for a variety of effects at a relatively inexpensive cost. A gloss varnish will deepen colors on a printed piece, while satin and dull finishes will reduce contrast. Varnish can be used in spot areas or flooded over an entire sheet for protection. Not only can varnish protect, but it can add depth, dimension and beauty to a printed piece. Tinted varnishes are also an option and offer soft tonal, transparent color. Learn even more about varnishes and coatings in our mill partner Sappi's Standard 3: Varnishes and Coatings. Or visit Verso's Ed #4: Protective Covering. Another great resource on varnish techniques can be found in this incredible 1999 piece called Varnish Techniques on Strobe.

T is Tooth

S is Swatchbook
A swatchbook is a delightful and helpful tool that allows you to touch and feel the papers of an entire line of paper. When you need to know exactly what a surface texture feels like or how the color looks, a swatchbook is a great way to review and make your paper choices. Mills create swatchbooks for each of their papers. Swatchbooks include charts for availability of sizes and basis weights. You'll find opacity, and caliper stats. They also contain key information about the paper’s green attributes and other product information such as envelope availability. Olmsted-Kirk offers them free of charge to aid you in your paper selection.
