DYMCO'S Vacuum Conveyor Serves Best for Varible Printing
SNS and email ads are popular, still we find direct mails in our posts.
Direct mails are made after printing different names and address on each mail.
This is what we call 'variable printing.'
It is done by inkjet printing. inkjet printing is written 'IJ' in short.
IJ automaticcally prints differrent info on each item.
IJ does not use plates, fixed info, like offset press or gravure printing.
IJ prints data and data is variable.
This is why inkjet can print different names, QR codes, IDs on every card and envelop.
Multi-product small lot is exactly the very feature of inkjet printing
in contrast to offset press and gravure printing that print the same data in volume.
Then what happens when you transport those cards and envelops fast enough in inkjet printing?
Due to wind pressure during transport,
corners and edges of these thin paper items may easily float,
and they may deviate from the initial position.
These situations result in printing failure.
Our vacuum conveyor sucks thin cards and envelops and transport them right under the inkjet head.
Landing height is kept minimum even for thin material like paper and films.
This high-speed and precise transport is essential for variable printing.
Sometimes it is difficult to export the whole suction conveyor overseas.
But we will make metal suction/ vacuum belts and give advise for designing the vacuum cocnveyor.
