A Necessary Evil for Printers?
The printing industry regards anti-set-off spray powder as a necessary evil. Working within production on a conventional printing press using spray powder you will commonly have a problem from time to time.
Spray powder is still the most commonly used method of preventing ink offsetting today. Anti-set off spray powder may have been the better choice for printers 20-30 years ago, but in today’s printing where heavy ink coverage and difficult stocks are sought after, spray powder has some issues.
With regular use powder falls onto the substrates which can all too often create problems with quality, leading to rework. Further to this, an unpredictable ‘powder bomb’ can hit the substrate and again cause quality to be substandard.
Spray powder finds its way into every part of the press and the surrounding components. Regular cleaning is necessary but time consuming and can potentially delay production.
The over use of spray powder and/or too large a particle size can also lead to problems when laminating, coating or varnishing. When applying coatings or laminates spray powder can cause surface roughness affecting overall smoothness and gloss.
Press rooms using powder find that can get into anything. This can find its way into expensive electrical components and machinery, causing damage and voiding warranties.
Inks take hours to dry after printing, how else can you speed up the drying process of print work?
UV offers a cleaner and more productive alternative to drying inks and coatings
Nowadays, packaging and commercial printing companies make use of UV presses, where ink is dried instantly with no mess.
