Paper & Boards
-
What goes into making paper? - Debarked, chipped wood, or other celloulose fibers
Wood free pulp - The solution is heated to 140 Celsius which produces a fibrous liquid known as pulp.
Paper qualities - Whiteness, opacity, strength, absorbency, finish, cost
Creating the perfect paper - The source of cellulose fibers, the sizing agency, additional finishes, the fillers that smooth out the finish of the paper
-
Internal sizing - Added to the pulp and affects the paper quality and the papers ability to run smoothly through machines
Surfacing sizing - Added to improve strength, reduce absorbency, and improves printability
Coated finishes - Coated paper reduces ink absorption which results in brighter richer and sharper images with deeper blacks. Increases smoothness and increases gloss and wet strength.
Uncoated paper - Not treated with any sealant. Allows greater and faster absorption of water or ink.
Paper and board finishes - Matt - Smooth, dull in appearance and good for any high quality print job. Satin - lower reflective levels than gloss
Gloss - Shiny
Strength factors - The way the cellulose fibers bond to each other, The strength of the cellulose fibers, the quantity of fibers used.
Tear testing - The elmendorf test calculates how much force is used to continue a tear in sample. Samples are partially cut and clamped into position. A pendulum tears the sample and continues to a resting point which is noted on a scale in Elmendorf units.
Folding - Means to create a shape, e.g. a box
Creasing - Paper or board involves making a line that is permanently present after the material has been creased or folded
-
Corrugated card - Made up of one or two flat outer layers called liners and a corrugated medium. it's shock absorbing, lightweight, and good thermal insulation making it perfect for packaging.
Tracing paper - Semi-transparent, grey colour. Good for tracing ideas and overlaying or transferring one image to another. Usually around 40-120gsm. It's hard and strong, Acid is used to treat the paper giving it it's transparency and making it resistant to grease
Layout paper - Slightly transparent but grater opacity than tracing paper. Not as strong as tracing paper. Often used in a sketch pad or large sheet format, and good for tracing ideas and laying our plans. Off-white colour around 50gsm
Bleed proof paper - Used for hand drawn marker renderings. It does not allow ink or solvent based marker pens to bleed through. Normally 70gsm
Cartridge paper -Has a creamy off-white colour, primarily used for sketching. Used with pens, pencils, pastels, crayons, inks and some paints. It has a slight texture.
Photo paper - Inkjet paper - Has non porous treated surface so image stays sharp Laser paper - Has surface coatings designed to permit the plastic particles in toner to melt and bond onto the surface of the paper Photographic paper - Has a photosensitive coating, reacts to light and the image develops over a short time
Mount board - Used for mounting photos and pictures. It's very strong, available in a wide range of colours, and good for making final models but IS expensive for prototypes
Bleached card - Highly brightened and treated on both sides. It is used for a range of products including high-end packaging and greeting cards. It holds print very well and has a luxurious feel to the surface. Usually available between 200 to 500gsm
Foil backed and laminated card - Enhances working properties. Foil linings create an impermeable layer protecting the contents from light, air, odour and bacteria
Duplex board - Twin layered board used for packaging. The top layer is normally white but available in a range of colours. It is food safe and can be coated to increase water and oil resistance. It folds, cuts and prints well. Usually around 200-500gsm
