OUGD504 Studio Brief 01 - Finishes (Research)

Finishes:
As part of the production process I want to add a finish to help enhance the design, this is something that I will apply to the front cover of my book.

Die-stamping:
Produces a three-dimensional low relief effect on paper or cover board. Like a heavy handed letterpress, with the additional assistance of a hollowed-out recess on the other side. A method of printing using an inked die to produce raised print. Made in steel or brass from artwork, either etched photographically like a process block, or engraved by a computer controlled machine tool. Used on book covers, greeting cards and logos on business cards.




Thermography:
A cheaper method to obtain a low relief. A fresh printed image is dusted with transparent thermography powder which sticks to the ink. When this is heated it swells becoming 3D, high-gloss and matte finishes are available. Sheets printed using thermography can become a problem if put through laser printers as it can melt.



Embossing:
Creating a raised image or design in paper and other materials. In one type of process, embossing dies come into contact with the wet pulp or damp paper under high pressure. This creates a raised surface. One way of embossing paper is to place the selected die directly onto a freshly pulled sheet and let the sheet dry on the mould. However, it is far more common and effective to impress an item into the sheet under pressure.

Another method of embossing involves using ready-made paper and running it through a printing press. The paper is dampened and pressed against a block or plate prepared by the embosser. Handmade, machine made and mould made papers all withstand this technique gracefully with fantastic embossing effects.



Foiling:
The transfer of a foil coating from a carrier roll of polyester, by means of a heated die. The coating can be metallic, matte, pearl or even a hologram. It uses heat and pressure to attach the foil to the substrate, either using a rotary method where it is applied in-line or using an off-line hot-stamping press.

Cold-foil stamping used on packaging are transferred to a substrate by means of a UV-curable adhesive applied to the substrate by either offset or flexo printing. Then the cold-stamping foil, comprising a carrier foil and stamping layer, is laminated onto the substrate. When the adhesive is cured, the carrier foil is stripped from the substrate. This process uses printing plates which is cheaper and can cut production times. Gradient and halftone iages cant be introduced.




Debossing:
The deboss process is the same as that for embossing, except debossing raises the material around the die impression rather than raising the design area itself. Brass, copper, and magnesium dies are used in the debossing process as well.
