What is design for print - Design production - Research

The information i'd like to / could include

- Choose substrate appropriate for print type
- Work with CMYK when dealing with screen to print
- Work to the size of the print out
- Use finishes to add to a product
- Spell check before printing
- Always do a pre-flight check
- Produce mock ups before printing final pieces
- Get several printing quotes, early on.
Learn roughly what things cost (unit cost) the more the cheaper
- Be aware the stock will effect the vibrancy of the print out, if uncoated it will be less saturated than that on gloss.
- Always work with 300dpi - High resolution for print out
- Composition - slug, bleed, columns, layout of book (imposition) 
- Finishes
- File setup
- Printing techniques

....

Think -



Stock:
- Weights (gsm)
- Finish gloss / matt / silk / coated / uncoated
- Laid or wove
- Boards Carton
- Plastics and acetates

Paper types

Newsprint: Short life span, cheap, used in newspapers and comics
Antique: roughest finish offered on offset paper, used to add texture to publications such as annual reports.
Uncoated woodfree: Largest printing and writing paper category - e.g office paper and photocopy paper
Mechanical: Produced using wood pulp, for short term use, eg newspaper
Art board: Uncoated board, cover stock.
Art: High quality paper, good printing surface, especially for half tones and where detail is important. Colour printing, magazines.
Cast coated: High - gloss finish 
Chromo: Waterproof coating on one side, good for embossing. Used for labels, wrappings and covers.
Cartridge: Thick white paper used for pencil and ink drawings. 
Grey board: Lined or unlined board made from waste paper. Packaging material. 

Size:

- A sizes
- SRA - oversize A versions
- Standard ISO sizes
- Imperial (North America) versus metric (Rest of world)
- Tabloid, Braodsheet, Berliner
- Envelope 'C' sizes
- DL size - Regular envelope


Print methods:

-Lithographic
- Gravure
- Screen print
- Flexography
- Pad - printing
- Six colour

Lithography:
Uses metal plate to transfer a design via a rubber blanket to the stock. Typically four colour (CMYK)
Wash print:
Allows most delicate of colours to be applyed to a substrate. Uses highly diluted ink to produce a flat colour which is subtle. 
Silk screen:
Imposes an image onto a substrate by forcing ink through a screen has has a design. Slow process, high quality. 
Letterpress:
Relief printing in which an inked raised surface is forced against a substrate. First form of commercial printing. Unique in its slight indentations through varying prints.
Hot metal printing:
The process of casting type in lines of molten metal. 
Thermography:
Used to produce raised letters on substrates. Powder dispensed onto sheet of printed paper, the powder sticks, when pushed through an oven fuses with substrate and leaves a raised surface.



Finishes

- Laminate - gloss / matt
- Foil blocking
- Embossing / de-bossing
- Spot W varnish

- Binding
- Folding and creasing
- Die stamping / drilling
