Finishing and Binding By Michael Simmons
Finishing A general term that applies to printing operations such as cutting, folding, perforating, die cutting, embossing, stapling, numbering, punching, drilling, and laminating.
Cuttingv/sTrimming Making larger sheets of paper smaller. Cutting off the uneven edges of paper Trimming the three sides to complete the inside of a book.
Paper Cutters Guillotine – used to cut large stacks of paper at one time. Clamp - holds the paper in place while the blade is forced through the paper Automatic Guillotine Cutter
Paper Cutter Cutting and trimming is an exact task. If inaccurate, waste can occur, which can be costly to the company. Some larger cutters have air jet beds that hold the paper down while they are cutting and moves it along the line to a finishing machine.
Automatic Paper Cutters Safety Devices Nonrepeat device – cutter blade will only come down once until reset. Two-hand operations – buttons on both sides of the machine so the operator must have both hands clear of blade. Electric eye stop – a sensor that stop the machine if a hand, arm or other object is its path Cutting shield with sensors – clear shield that must be closed before machine will cut
Paper Cutters When replacing blades use extreme cautions and wear proper safety equipment. When out of order use lock-out-tag-out Automatic Guillotine Cutter
Inside paper folder
Going Green Recycle trimmings and incorrectly cut paper
Folding Machine Smaller folding machines use rollers to bring the paper in. The paper is carried to a folder plates, the sheet buckles and is forced again a combination of rollers fold the paper. Some folders use a folding knife to force paper between the rollers. Different types of folds.
Folder Safety Tie back long hair Secure loose clothing and jewelry Keep figures clear of pinch point such as rollers Turn off and unplug machine before removing jams.
Folding Machine Operations A – paper is fed in to the machine by rollers B – Paper hits the stop on the fold plate an buckles down C – Rollers catch the paper and feed it down towards the folding rolls
Other forms of Finishing Perforating – placing a series of small cuts or slit in the substrates (ie. coupons) Die Cutting – A process in which pressure is used to force a sharp metal die (steel rule) through the stock. Used to make irregular shapes. Embossing – creates a raised image on the substrate. Substrate are pressed between two dies, one is relief and the other is recessed. The image can be raised or sunk in (debossing) Stamping (foil stamping) – a method of transferring a thin layer of metallic tone or color to the substrate using heat and pressure.
Other forms of Finishing Numbering - imprint tickets, certificates, checks or other item with consecutive figures. Punching – piercing operation done by forcing a metal rod down thorough the paper to remove stock Drilling – piercing operation that uses a revolving hollow drill bit with a sharp base. The waste stock is raised through the hollow center of the bit. Laminating – boding of two or more material together to become one common until. Usually a thick plastic film rolled over and under the substrate and heated sealed together.
Binding The process of joining together multiple pages of a printed products by various means including sewing, stapling, spiral metal/plastic wire, and adhesive.
Basic Binding Types Adhesive Binding– also know as padding., the uses glue or adhesive compound that holds the sheets together, but also allows them to be removed. Mechanical Binding (loose-leaf binding) – broad category that includes different devices used to hold the sheets together.
Types of Mechanical Binding Spiral wire Metal posts Metal/Plastic rings Plastic combs Channels that rely on friction to work
Basic Binding Types Side Stitching – a form of stapling in which metal wires is forced through the sides of the sheets and formed to hold the sheets together. Saddle Stitching – metal wire (staples) forced through the folded edge to hold the paper together. Perfect Binding (soften cover binding) – uses an adhesive to hold the sheets together and to fasten the flexible cloth or paper cover onto the body.
Basic Binding Types Editing binding (case binding or hard binding)– the most complex and permanent form of binding. A rigid cover is attached to a book body that is held together by sewing. Some times uses thermal tape.
