In order to effectively manage waste in a press, lets look at further classifications and then dwell on process and areas where we can monitor, control and manage waste..!
1. Tare waste (Wrapper waste)
2. Mat Waste (Tear sheet waste)
3. Reel end waste (Core waste)
4. Sweep Waste (Scrap waste)
5. Print Waste (Bad Copies waste)
Lets look at the costeliest yet controllable waste out of the aobe five categories which is the PRINT WASTE-
What are the factores that contribute most towards generating higher Print Waste?
Press Condition- A press which is ignored for prevantive and routine maintenance by the press crew will obviosly generate higher waste. Does the operators and maintenance staff understand the press well, have they been trained by the supplier? Normally the focus is on production and as long as the crew is able to deliver production the machine problems are ignored, deficiencies are patched up which subsequently result in break downs or excessive wear and tear of critical components directly effecting Print quality and generation of non sellable copies.
A good printer will understand that any deficiency in print quality may have originated from a dormant press problem which is being overlooked. Check for unhealthy signs in the printing operation before it suddenly surfaces and when it is too late...!
Normally the maintained scheduled times are considered as non productive , part of down time of the machines . this is a dangerous perspective . the management and print crew should recognize the print need for allocating adequate time for maintenance.
The machines maintenance. In short, is identifications and eliminations of each and every factor that limits quality, reduces speed lengthened make ready time and these factor are being the waste factors , there are simple strategies to be adopted , while attending the press.
