Pinbar Hole/Plate Stretch

Pinbar Hole/Plate Stretch

To hold polyester plates in secure register at the Master Cylinder, use a fine mist of Elmers’ Spray Adhesive on the back side of each plate. This will add significant grip-shear-strength between the plate and cylinder surface and reduce stress at the clamp or pinbar. Elmers’ Spray Adhesive cleans from the plate cylinder with press […]

Pre-Mix Fountain Solution

Pre-Mix Fountain Solution

A few minutes saved each day/shift adds back extra hours in billable production at the end of each week. Always pre-mix fountain solution in volume to eliminate non-productive trips to the water faucet. Mix a gallon a single press, five gallons if using multiples. The most productive (and profitable) multiple-press shops I’ve visited use stackable […]

SpeedyDry Ink Drier

SpeedyDry Ink Drier

Although the manufacturer won’t let me sell it (not because I didn’t try), SpeedyDry is the most effective and forgiving ink drier that I know of. With most other ink driers, the makers recommended adding 3 to 5 to 8 percent by volume to ink, but if you add a bit too much, its effect […]

AB Dick Feed Table

The soft sheet-metal feed table on AB Dick’s direct feed presses is prone to ‘self-damage’ if allowed to jam into Micro Lateral Guide. When this happens, the ‘forward edge’ of feed table is bent down at its’ center, reducing support to the forward ends of paper support rails. A bent feed table does not suffeciently […]

Back-Cylinder-Packer

If you want to print a uniform screen or solid accross the varying layers of an envelope, stick a layer (or 2 ) of Duct Tape on the impression cylinder and create a Back-Packer. A layer of compressable Duct Tape behind the image area conforms to the thicknesses of the back-side of the envelope producing […]

Extra Paper Delivery Dollies

Time is money. Why waste valuable press time unloading/re-handling freshly printed sheets to reuse a single paper dolly? If you do you are losing money! Extra press delivery dollies save press time and reduce risk of ‘causing’ offset. If you use multiple presses of same model, having extra paper dollies is a no-brainer.

Weak Impression Springs

Weak Impression Springs

Presses with ridgid impression control can vary gap volume and apply the necessary impression pressure to print fine detail on heavily textured stocks, but AB Dick, Ryobi, and Itek direct feed models lack this control due to the use of impression springs. If you have Ryobi or Itek presses and find that you must over-ink […]

Adhesive Spray Booth

Applying spray adhesive onto backs of Polyester plates is an effective way to reduce plate stretch but is also messy. I have seen some pretty sticky/messy presses where operators coat plate back-edges by lifting plate tail-ends and spraying adhesive on the press. An innovative Pressman from Sacramento, California uses a small ‘Spray Booth’ constructed from […]

Using Kompac II KwikVac System

The Kompac KwikVac System utilizes the suction developed by a strong hand-operated Suction Bulb with one-way valves. Suction from KwikVac sucks up waste solutions directly from Kompac nip thru tubes in TimeSaver Seals, automatically transfering liquid waste into waste container at backside of press. As you print, wetting solution used is automatically replaced as needed […]

Calcium Control in the Dampener

Calcium Control in the Dampener

Over the past 15 years North American Paper Manufacturers have changed from an acid to an alkaline process for making printing papers. First with copier papers where paper’s PH mattered little, but when exposed to fountain chemistry of the printing process, calcium carbonate, styrenated starches leaches away from the paper and into the process from […]

Use Velcro Strip To Stop Stock

Stick a 2″ pad of adhesive backed Velcro onto your paper stop plate at impact area of delivery to reduce lead-edge impact with coated stock. This will improve sheet delivery/stacking at high production speeds and eliminate lead-edge denting/marking. Velcro pads are available at most all Fabric and Sewing Material Stores.

Sensitized Ink Rollers

Over time soft ink rollers become sensitized from chemical and physical contaminations of the printing process. Soft roller pores collect contaminates such as ink pigment, dye, clays, calcium carbonates and other paper bi-products which creates a ‘barrier’ to ink, causing rollers to reject ink once water is introduced into the inking system. Roller surface sensitization […]

Care of Alcohol Dampener Rolls

Proper roller maintenance is critical to keeping your alcohol dampener in good condition and operating at its optimum. Metal rollers must be kept clean, smooth and free of oxidation, and soft rolls must stay soft and sensitized to remain hydrophobic and ink free. Metal rollers can be cleaned with most good quality plates cleaners, then […]

Powder Your Fingers

Powder Your Fingers

Have you ever caused inky/greasy finger prints to soil your stock when loading (or unloading) the press and were forced to stop to wash your hands before continuing? If you have, here is a quick and easy ‘temporary’ solution to having inky hands. When you have messy hands and are in the middle of something […]

Ink Roller Maintenance

Rubber rollers are manufactured with a texured surface which is produced by a spinning grinder wheel. The the hills and valleys of the textured surface is what provides the grip/surface that allows ink to adhere to and flow from roll to roll thoughout the ink train. When the roller’s ‘valleys’ become plugged, the rollers surface […]

Lubricate Kompac Fountain Bottle Cap

To reduce friction and wear on your bottle cap and O-ring seal, wipe a thin film of Petroleum Jelly around the O-ring area. This not only reduces friction and wear when installing and removing bottle, it allows cap to seat and seal more easily/consistently for consistent solution dispensing. To further reduce the force required to […]

Cleaning & Refreshing Kompac On-The-Fly

The liquid holding capacity of the Kompac causes wetting solution to contaminate faster than dampeners with greater fountain capacity. On long runs, fountain contamination caused by paper surface sizing, spray powder, and chemical neutrizers collect and concentrate in Kompac wetting solution. Some papers which are ‘too neutral’ ( high alkaline) can raise fountain PH from […]

Lead-edge Ink Build-up W/Kompac

Plate lead edge ink build up is caused by excessive form roll pressure due to too heavy of a form roll to plate setting or a loose Kompac. The Kompac II form roll ink stripe to a dry plate should be no less that 1/8″ and no greater that 3/16″. A setting greater than 3/16″ […]

Tone Lines Accross Sheet W/Kompac III

Tone Lines Across Sheet with Kompac II

The most prevalent, and miss-diagnosed problem experienced with the Kompac Dampener, is the ‘solution to’ eliminating tone bars from accross the sheet. I have communicated with printers from many countries regarding this issue, and heard horror stories of costs related to solving it, from completely re-gearing a press to installing a new press with a […]

Twist The Pile

Twist The Pile

When handling freshly printed carbonless stock, you can quickly and effeciently separate the printed sets with this simple technique. The last sheet of a carbonless set is not coated, nor it the top of the first sheet, and, as a result, there is much less friction between these sheets than those that ‘are’ coated within […]

Wet-Sanding Kompac Metering Rolls

Kompac metering rollers are made of a unique hard Engineering Plastic that was called ‘stone plastic’ by its inventor but now known as Delrin or Acetal. New Kompac metering rolls are surfaced on a precision high speed lathe which leaves a fine uniform surface with a ‘tooth’ that provides a surface grip that holds a […]

Service Tip – Checking your Kompac unit

Take the Kompac off the machine and separate the rollers. Place the Kompac on a sheet of white bond paper on a light table. Bring the rollers slowly together until they just touch.- make a complete revolution of the rollers. No light should show through. Light would show only through depressed spots in the rollers […]
