- 1Arc Cut Causes/RemediesCause: Pile is clamped at sides only
Remedy: Use flexible clamp plate - 2Hollow Cut Causes/RemediesCause: Pile is clamped at sides only
Remedy: Use flexible clamp plate - 3Cut in Form of Stairs Causes/RemediesCause: Clamp pressure too high, surface characteristics of materials, knife grinding angle too acute
Remedy: Reduce clamp pressure, fan sheets out and use lower piles, change knife - 4Bulge Cut Causes/RemediesCause: Pile not fully clamped at cutting line, knife enters the pile before full clamping pressure is attained, too little to clamp pressure
Remedy: Use wedge sharp clamp, two-step clamping, increase clamp pressure - 5Overcut Causes/RemediesCause: too much clamping, blunt knife, faulty setting of back gauge
Remedy: reduce clamping pressure, change knife, check back gauge setting - 6Under Cut Causes/RemedyCause: Clamp pressure too low, cutting material rough or uneven, faulty back gauge adjustment
Remedy: Increase clamping pressure, check clamp pressure and adjust, check back gauge setting - 7Wavy Cut Causes/RemedyCause: uneven clamped material, knife grinding angle too acute, knife too short
Remedy: flexible clamp plate, change knife - 8Wavy Cut (Printed Sheets) Causes/RemedyCause: Uneven clamped material, knife grinding angle too acute, knife is too soft
Remedy: Flexible clamp plate, change knife - 9What is mechanical joggingMachine vibrates and jogs paper to the corner
- 10Why do we remove air?So the pile below doesn't move the clamp
- 11Plan the cutting sequence1. Find press register
2. Rule up one press sheet
3. Measure and mark sheet until last cut
4. Draw layout sheet showing cutting sequence and dimensions for cuts
5. Program cutter
6. Test cut one sheet - 12What is a built padYou put it on the block to make the body the same height as the spine
- 13Cutting RulesCut #1 opposite press register, Cut #2 opposite press register, continue around each side of sheet, Same direction of turning if possible, minimize # of cuts, minimize amount of handling, cut from large to small with back gauge coming forward
- 14Cutting ProcedureAccess program, load paper, jog between each cut, press foot pedal, press cutting buttons, take away trim waste, move blocks to side if necessary, remove good product, repeat cycle

Headbanding - 19PVA - Polyvinyl AcetateDries fast, creates strong flexible bond, water-soluble, irreversible, doesn't mold if mold killers are added, don't let it freeze
- 20MC - Methyl CelluloseDries slowly, creates weak or no bond, reversible, doesn't mold, can be stored at air temp if in air tight container, mix with PVA for slow drying, comes in powdered form, can be thinned or thickened
- 21Pastedries slow, fairly strong bond, water soluble, molds quickly, can be stored in fridge, made from wheat or rice starch, can be tinned or thickened
- 22Animal Glue - GleatinVery strong, fairly fast drying, reversible, can mold, must be hot
- 23Why jog sheets?Quality, consistency, productivity, speed
- 24How to pick a jogging systemQuality, accuracy required, size of product, cost of system
- 25Types of joggersFlat, corner, static, vibrating
- 26Types of countingManual, measured, weighed, mechanical & optical
- 27Choose a counting systemQuantity, size, accuracy, budget/availability
- 28Film Lamination DefinitionThe process of bonding a thin transparent layer of film to the surface of one or two sides of a piece of paper or other stock
- 29Why Film Lamination is commonly used?Decoration, stiffness, protection, gloss, coating
- 30Film Lamination MethodsWet - solvents or water and adhesive is applied to the film as the silk is applied to the paper
Thermal - uses heat to bond the film which had a pre-applied glue to the stock - 31Film Lamination FinishesGloss- adds shine and enhances colour
Matte - Adds dull flat finish keeps colour quite true
De-lustered - unique, silky to touch - 32Layflat Film LaminationIdeal for prefect, case, coil, and stitch bound book covers, generally common things
- 33Polypropylene Film Lamination1 Sided films, have self-adhesive properties
- 34When is SureGrip used?When jobs won't adhere properly
- 35BioLamThermal lamination used to kill bacteria
