Pounce is gently sprinkled all over the writing on the paper. When using a quill or a steel nib, and with inks that are made up to match those typically in use during the 18th and 19th centuries, and provided the pen has been used with the fine strokes typical of handwriting of that period, the handwriting will be sufficiently dry within 10 seconds to allow the paper to be folded without blotting.
However, because dyes are dissolved in the liquid phase, they have a tendency to soak into paper, potentially allowing the ink to bleed at the edges of an image. To circumvent this problem, dye-based inks are made with solvents that dry rapidly or are used with quick-drying methods of printing, such as blowing hot air on the fresh print.
Ink requirement is defined as the amount of ink needed to print a unit area with a standard Solid Ink Density. For newsprint, the ISO 12647-3 specification is C 0.90, M 0.90, Y 0.90 and K 1.10, Status E, D50, 2o, density minus paper with polarization filter. Ink requirement is measured as g/m2 (grams of ink required to print 1 m2 of paper)
The paper is then dusted with a powdered polymer that adheres to the ink. The paper is vacuumed or agitated, mechanically or by hand, to remove excess powder, and then heated to near combustion. The wet ink and polymer bond and dry, resulting in a raised print surface similar to the result of an engraving process.
A correction fluid (or correction liquid) is an opaque, usually white fluid applied to paper to mask errors in text. Once dried, it can be handwritten or handdrawn upon. It is typically packaged in small bottles, with lids attached to brushes (or triangular pieces of foam) that dip into the fluid. The brush applies the fluid to the paper.
A dampened paper may be produced by soaking a piece of printing paper, or any other papers that are slightly water-absorbent but are not water soluble, into a tray of water for about 5 minutes. Afterwards, the paper is laid onto a towel and dabbed dry. The moist paper allows ink to be drawn out from the burred lines of the plate when it is ...
In printing and graphic arts, mixing of two dissimilar colors in two adjacent printed dots before they dry and absorb in substrate is referred to as color bleeding. [1] Unless it is done for effect, color bleeding reduces print quality. Prior art applied this term to the phenomenon of single color ink following the fibers of the paper. [2]
In printing, anti-set-off spray powder is used to make an air gap between printed sheets of paper. This enables the ink to dry naturally and therefore avoid the unwanted transfer of ink from one printed sheet to another. The problem can occur with most types of printing.
