Paper and Board…
Since the creation of paper in Egypt from the papyrus reeds, which is where the word paper originated from, paper has been fashioned according to people’s requirements and the availability of local materials.
Some of the main papers used in commercial printing are coated and un-coated papers. Coated papers have 3 types surface finish. Gloss finish which would generally be used for brochures, posters or hand outs. Matt & silk finish which has a similar usage, but is slightly bulkier and softer look to it. Coated papers reduce the ink absorbency into the paper giving sharper, cleaner image.
Uncoated Papers are of high quality and have a natural look and feel. The properties are good strength, high brightness and good archival characteristics. They provide a non-glare surface suitable for reading and writing. Usage would be business stationery, school text books and annual reports.
Paper Weights Explained
Paper is supplied in various weights, referred to as grammage, which depicts the weight sheet of paper in grams per square meter (or AO size). Paper is usually defined any weight between 70gsm and 170gsm and a board would be anything 200gsm and upwards.
Another method of measuring paper is thickness, which are microns or mics. (1micron is equal to 1000th of a millimeter). The thickness of paper is married closely to the weight of paper, as the weight increases, the paper thickness increases.
With the world becoming more environmentally conscious, a bigger effort is being made to reduce deforestation. With introduction of the Forest Stewardship Council in 1993, who is dedicated to promoting responsible management of the world’s forests.
There has been an increase in the availability of recycled papers to accommodate clients who need to reduce carbon footprint on the environment. Such as Revive paper and Cocoon paper.
Paper has been around since the start of civilization and even with the introduction of electronic media, it will be around for a long time yet.
