Unit 6 Processing Papers and Boards Flashcards
How can the shape and form of papers and boards be manipulated
Creasing
Scoring
Bending
Craft Knife
Die-cutting
Laser Cutting
What is the difference between creasing and scoring?
Creasing compresses cellulose fibres
Scoring makes a partial cut
How do we overcome bending issues?
Materials can be cut into sections and reassembled with gaps between parts to emulate a crease/score
What is used for cutting in a die cutter?
Sharp blade
What is used for creasing in a die cutter?
A blunt blade
What is a kiss cut in die cutters?
Peel and Stick products (labels)
What is advantages of a flat bed die cutter?
Energy efficient
Can be changed quickly
More useful for low volume production
What is advantages of a rotary die cutter?
More efficient
Accurate
Less waste achieved
What is a disadvantage of rotary die cutter?
high on set up costs
What are advantages of die cutting?
Fast
Thick materials can be cut without burn lines
Can makes creases
What are cons of Die cutting?
high set up cost
What are pros of laser cutting?
Easily edited in cad
can cut more than just paper/board
Ideal for bespoke products/short runs
Can cut more intricate designs
What makes paper and boards so able to be glued
adhesive is able to sink into the surface very quickly and
easily due to them being absorbent
Non flammable,non toxic,solvent free
What are VOCs
Volatile organic compounds
Water based adhesive
Non toxic,white glue that dries clear
Needs to be applied thin to prevent wrinkling
Solvent based adhesive
Dissolves the surface of a material allowing parts to be fussed together
Toxic
Hot melt adhesive
Quick dries quick not suitable for heat sensitive materials
Spray adhesive
Gives thin and even coverage
Can be difficult to control
Doesn’t give wrinkles
Contact adhesive
Applied to both surfaces and left to go
tacky – it bonds on contact
Clamps are not needed
Can bond dissimilar materials but not thinner
paper/board due to being too wet
Difficult to apply discreetly due to thick yellow
colour
Some adhesives are brittle once dry but contact
Adhesive tape
Various widths,colours,strengths,transparencies and finishes
Most cause damage
Fixing with components
Paper and board fixings allow dissimilar materials
to be joined instantly e.g. rivets and eyelets
They can create spinning parts and add
reinforcement
Rivets also add an aesthetic accent to key
features
