A Private Watermark provides both security and authenticity. It cannot be removed, altered or duplicated. It is a permanent part of the paper.
Cotton is one of the strongest and most durable natural fibers known to man. Papers manufactured from cotton fiber will last longer and hold up better under repeated handling and various environmental conditions than paper made from wood pulp.
These rags were cleaned and then broken down into fibers, which were then used to manufacture paper. In a sense it could be stated that the fine paper business has been engaged in recycling materials for production since its very beginning.
Wood pulp is processed into sulphite, which is then used to manufacture various grades Is watermarked paper paper. It is more economical than cotton fiber however, it is also less durable and more acidic than cotton fiber. There are different grades of sulphite, depending upon how much processing has gone into making the pulp.
Processing includes breaking the fiber down to very fine pieces and bleaching the natural color out of the wood to attain a high level of whiteness. The very best grade of sulphite is known as a 1 sulphite. Southworth uses only 1 sulphite in the manufacturer of its fine business paper.
This is particularly true as the percent of wood pulp in paper relative to the amount of cotton increases, since cotton fiber papers are less likely to disintegrate or yellow than papers made with all or part wood pulp.
All cotton fiber paper is sized at some point in the manufacturing process. Sizing is a starch. Cotton fiber is absorbent. Without sizing, when ink is applied to the surface of the sheet, it will bleed through the fibers causing a blurred look.
Size seals the fibers and helps control the degree of ink penetration into the paper. Sizing also contributes to the crisp, unique feel of cotton fiber papers. How the sizing is introduced to the paper will affect the finished characteristics of the sheet.
Sizing is typically introduced at one of three points during the manufacturing process: Sizing introduced at the wet end means that the sizing is added to the mix at the beginning of the manufacturing process so it is permeated throughout the sheet.
This is desirable for economy and also for fine papers that will ultimately be used in high-speed copy machines and laser printers.
In-line sizing means that the size is applied to the surface of the finished sheet in line after the paper has been manufactured but before it is dried and calendered.History. The origin of the water part of a watermark can be found back when a watermark was something that only existed in paper.
At that time the watermark was created by changing the thickness of the paper and thereby creating a shadow/lightness in the watermarked paper. PAPER TYPES.
Paper can be separated into two main categories: uncoated and coated stocks. Uncoated stocks: Uncoated stock is paper that has no coated pigment applied to reduce the absorbency or increase the smoothness. The paper is great.
We use it for our law firm and printing final drafts of estate plans. I am so annoyed at the packing though. Our shipping box was completely intact but inside, 5 out of 7 reams were ripped open and had damaged paper.
If watermarked bond paper without the stamp was used for the copies, no meaningful source data would be displaced but the watermark could still be viewed under certain circumstances, as on a light table.
Securing Digital Image Assets in Museums and Libraries: A Risk Management Approach. Paper, the types, sizes, thickness and finish; it can all become a little complicated, This go to guide will help you to choose the paper fit for the job and make the whole process just a little less stressful.
