2 ZAC system Why ZAC system is excellent? Because ZAC system can calculate necessary replenishment. So dot image always stable condition (±1.0 less at AM175L and ±2.0 less at FM20) with minimum chemical(75% less than non ZAC). Why? ZAC system continuously checks chemical condition, and calculates required replenishment. You can get minimum replenishment=min CO 2 How ZAC system can calculates processing fatigue and carbon dioxide fatigue. And It corresponds to environmental change.

3 ZAC system How Stable chemical condition means stable pH of chemical condition. But measure device of pH is too expensive and difficult maintenance. So we adopted electric conductivity device which has correlation with pH. *Electric conductivity (EC) device is easy maintenance and reasonable price. We developed new method of calculating electric conductivity to pH. Why difficult? Next.....

4 ZAC system Why difficult? (1)-(3)samples are same pH but all electric conductivity is not same. Because number of K + are different. pH 13 Only oxide Only processing neutralize pH 13 (1) (2) (3) *Actuary there are too many K + and OH -. Original condition

5 ZAC system "ZAC system" is considering proper electric conductivity continuously. So you can get stable pH condition.=Stable dot condition. Image of "ZAC system" control "ZAC system" adjust chemical automatically. You can maintenance easily.

6 ZAC system Why difference of target EC and measured EC is occurred? Environmental In case of high carbon dioxide is occurred. For example to use heating air conditioner in winter, or when using it in a close room. Processing In case of to many(/small) processing. High(/low) image pattern of CtP compare with average pattern. The quantity consumed is different day by day. "ZAC system" can control proper condition continuously if situation is changed.

7 ZAC system If you do not use "ZAC system".... In case of replenishment method at the passing time and processing. Normally this method is decided by too much replenishment. To waste useless replenishment and not guaranteed stable condition.

9 You can get stable condition with minimum replenishment ! Test result of compulsorily changing environmental condition and amount of processing. LH-PJE+ZAC ZAC system

10 ZAC system You can get stable condition with minimum replenishment ! Results of our customers who adopt ZAC system. Customer name Total Total (L) DT-2RE(1:6) ml per Company A14, Company B7, Company C16, Company D16, Company E3, Company F28, Company G23, Company H5, Company I75, Company J31, Company K8, TOTALS232,7722, Data represents the usage of 10 months.

11 ZAC system You can get stable condition with minimum replenishment ! Comparison by John Zarwan 8-up 1000 /month 4h on/8h standby 5days week(22days/m) Typical operation 75% less than Non ZAC!

12 ZAC system Comparison of ZAC system and non ZAC system. ZAC system Non ZAC When you process different size from the average size. × When you process different from the average image area rate. × When the amount of processing changes. When the density of environmental carbon dioxide changes. × When the environmental humidity changes. When the dilution rate of the developer changes. Easiness in sensitivity setting. × Easiness of set value setting.
