TOP-ONE CF502
Innovative Product!! Eco-friendly Offset Print Super Technology
Photocatalytic reaction device is built-in and it activates dampening water.High-quality print is possible without using conventional chemical.
We support “Eco-friendly Offset Print”.
This system removes calcium and magnesium from tap water, and significantly reduces its surface tension. You get a better print quality at lower cost, since no conventional chemical but only tap water is needed. (Condition differs from printing environment.)
Ultimate chemical free system was completed by integrating the combination of photocatalytic water processing unit and magnetic water processing unit, and Cosmotech’s manufacturing technology of dampening solution circulation system. TOP-ONE CF502 contributes “eco-friendly offset print”.
Features
- No conventional chemicals required for dampening water.
- Waste liquid is reduced and be an eco-friendly printer.
- The ink mileage improves because minimum water is used for print.
- No damage to CTP plates and rollers.
- Sewage drainage is possible since chemical isn’t contained.
(Confirmation by an ingredient analysis is necessary for sewage drainage.)
Chemical free system
Photocatalytic Water Processing Unit
By using photocatalytic reaction by oxidation titanium and a UV lamp, dissolved oxygen in the water is reduced and the oxidation-reduction potential of water is lowered. This regenerated water is expected “decomposition of dirt”, “antibacterial activity”, “antiseptic property” and “harmful substance removal”. Also, osmotic strength to hydrophilic non-image part of PS plate becomes high by a decline of the surface tension. Even if ink mixes with dampening water, because chemical isn’t contained, chemical reaction isn’t initiated and a phenomenon of variation in ink thickness by color doesn’t occur. By this, it is possible to maintain the most suitable balance of dampening water and ink, and higher quality of print can be achieved by small amount of dampening water and ink.
Magnetic Water Processing Unit
Magnetic water processing unit has the effect of settling red rust and impurities in the water down to the tank lower part. So it prevents scale and dirt from accumulating on the circulation system (piping system, circulation tank, printing press). TOP-ONE ECO CF502 removes residue deposited already in the printing system little by little. The endurance of the longer effect can be expected by installing a dampening water filtering system PC-500D.
Also, it has the effect of subdivision of water particle (1/13). By synergistic effect with photocatalyst, surface tension falls and ability to penetrate increases.

Before Installation
| Usage of IPA | 18 litter x 1 can/ day → 12.5 cans/ month 1 can JPY3,000 x 12.5 = JPY37,500/ month JPY450,000/ year |
|---|---|
| Usage of Etch solution | 20 litter x 4 cans/ month 1 can JPY16,500 x 4 = JPY66,000/ month JPY792,000/ year |
| Amount of waste liquid | 150 litter x 4 times (Water exchange once a week) → 600 litter/ month Industrial waste disposal cost JPY90/ litter x 600 = JPY54,000/ month JPY648,000/ year |
| TOTAL | 450,000 + 792,000 + 648,000 = JPY1,890,000円/ year |
After Installation
Cost of chemical and industrial waste disposal cost can be reduced substantially.
