- You should understand the cost of whole process,
as cheaper machines end up with higher costs in the first year
itself due to losses not accounted for during purchase i.e. ink
costs, energy costs, plate costs, downtime costs, bad quality costs,
lower yield costs.
- Ink cup system should be closed so that ink
and solvent loss through evaporation can be saved and ink can be
prevented from dust, dirt particles.
- Machine needs to have special cross table with
X/Y/Z axis , so that the component can be shifted according to
the precise printing position. This saves time.
- Machine needs to have suitable facility for quick
change-over of ink cup and etched plate, so that multiple jobs
can be done in limited time. Also the accessories for consistent
print quality should be available with machine.
- Proper ink storage system in the ink cup
should be available. If, suppose during emergency, such storage is
required.
- An advance machine should have membrane keyboard
with the following panel functions -- inching mode, single
cycle, continuous run, multiple print, infinitely variable speed
regulation, infinitely variable doctor contact pressure, adjustable
doctoring pressure. When less variables are to be printed these can
be avoided.
- You need to have clear idea of the quality desired
(fine printing is only possible with sophisticated technology
like high quality cup ring, metals for fabrication).
- Understand, if the supplier or manufacturer is
competent enough to provide all solutions at his premises
i.e. designing studio, plate and pad making facility, fixture or
jigs making, ink and pantone preparation, ink testing, sampling
facility, technical feed backs, after sales service, machine
guarantee, so that you need not run in different directions for a
single product printing.
- Machine only that machine, which can serve your customized
purpose (flexible speedy machines suitable for multicolor and
automations requirements).
- Select the machine that can cover maximum printing
area, which can be sometimes 360 degree as per the requirement.
- Manufacturers or suppliers should have proper set
up (designers, engineers, technicians) to guide you when
required, as well as display system at their site (showroom etc).
- Machine needs to be environmentally suitable
so that it consume minimal ink. Evaporation of solvents should be
very low.
