Chemical cleaning
More efficient production starts with consistent color strength
Daily cleaning is critical given current standards for printing inks and the use of increasingly fine anilox rolls. To ensure a standardized transfer in volume, the
it is necessary to clean at every color change.
This cleaning can be done manually daily using an automatic dosing system or periodically.
Manual cleaning
For manual cleaning, the employee puts a bucket of detergent on the pump after each color change and circulates it for at least three minutes.
It then runs the normal wash program in order to rinse out the detergent and/or flush for two minutes with clean water if the wash program is not present.
For manual cleaning, Grafilox has several cleaning agents in its range.
Automatic dosing system
If your printing machine has a semi-automatic or fully automatic washing system it can be equipped with an automatic dosing system (by means of a 24 Volt signal). The dosing system cycle is designed with efficiency and effectiveness in mind:
- The minimum wash program lasts 5 minutes.
- During this cycle, the cleaner is dosed, using 40% of the cleaning time for this process.
- The remaining 60% of the time is used to thoroughly flush the cleaner out of the system.
- The dosage of the cleaner depends on the number of color changes and varies between 0.3 and 0.8 liters per cleaning cycle.
The dispensing system allows for controllable volume loss and daily cleaning. This ensures consistent print quality and prevents unplanned downtime. This ensures consistent and reliable cleaning performance.
Periodic cleaning
Periodic cleaning is essential because there is no cleaning system that cleans 100%. It is therefore necessary to perform regular periodic cleaning. For example, twice a week for used anilox rolls.
This can be done by using Grafilox Anilox Cold. It is mixed at a ratio of 1 to 4 with water and added directly to the pump during the printing process.
The solution then circulates for a minimum of 30 minutes to a maximum of 1 hour as normal printing ink, providing thorough cleaning.
