Keys of mounting plate 貼 版 要 點

1. 溫度 (temperature)

原 因 (factor):

避免因溫度原因影響粘結力
--冬天避免將膠帶置於嚴寒環境中
--夏天將膠帶儲存於擁有空調設備的房內
Avoid temperature factor effects the adhesion:
--No expose in frost cold conditions in winter.
--Store in a room with air conditioner in summer.

德莎膠帶設計可在寬溫度範圍內使用
--但膠粘劑在標準溫度環境下發揮最佳性能
--最好將膠帶置於貼版區24小時以後使用
Tesa tapes are designed for wide range of temperature
--Yet the adhesive works its best functions in normal temperature.
--It's better to use the tapes after placing it in work area for 24 hours.

 

在室溫下進行
process in room temperature

2.清    潔 (Cleaning)

對版輥及版材最佳的清潔效果
The best cleaning effects to roller and plate

- 灰塵, 鐵, 油墨 … 會破壞粘結力
可導致粘結不佳及翹版現象
-Dirt, iron oxide, printing ink, etc. will weaken the adhesion, which will cause defective adhesion and warp of plate.

其他化學溶劑可能會破壞套筒,版材
Other chemical solvent may spoil the roller and plate.

- 100% 酒精也可使用-- 揮發速度更快
- 儘量減少醋酸鹽類溶劑使用: 清潔變得容易但一些化學作用可能破壞到套筒和版材
-100% alcohol are usable, which will evaporate sooner.
-Avoid using acetate solvent, which will be easy to clean but may spoil the roller and plate.

用50%的酒精與水混合
溶液清潔版材和版輥.
Clean the roller and plate with 50% alcohol and water mixture.

3. 膠帶大於版材面積
Tape should be biger than plate

    減少翹版的風險
 To reduce the risk of warp

- 更大的膠帶面積提供更強的粘結力於鋼輥或套筒.
- 建議預留 10mm 以上邊緣
-The biger measure of tape provide a stronger adhesion on roller or sleeve.
-Suppose to preserve a edge no less than 10mm.

膠帶的邊緣需大於版材的邊緣.
The edge of tape should be wider than of plate.

4. 結合錯位(Stagger the combining )

    減少翹版的風險
 To reduce the risk of warp

版材貼住膠帶介面起到密封膠帶作用
儘量將非印刷或實地部位置於版材上方
Plate stick on the interface of tape to seal it up.
Put the no printed or full point printed area on the interface as far as possible.

膠帶的介面應與版材的介面錯開.
To stagger the interfaces of tape and plate.
正確貼膠帶方法
The correct mounting method

1. 貼膠帶 (Mount the tape)

在貼膠帶時運用一塊刮版平均的刮貼膠帶.
避免氣泡的產生
To avoid bringing bubbles, please use a board to scrape the tape equally when mounting.

   - 得到更高的壓力,將膠帶緊密地貼合在版輥表面
-To gain a larger pressure, which make the tape stick on the surface of roller firmly.
      
          Phand= 104Pa       Psueegee= 5*106Pa

步驟一 (step 1)

2. 固定版材 (Fix the plate)

先將版材的一小部分固定於膠帶.
Fix a small part of plate on tape first

使用離型紙避免版材與膠帶非必要的接觸.
Using the separating paper to avoid the touch by mistake.

避免因貼版不準確而產生套印問題
Avoid chromatography problem by inexact plate mounting

- 在版材重新定位時避免膠帶帶起
- 在某些擁有貼版台的貼版機上無需此操作
-To avoid stick the tape off when reposition.
-This action is not necessary in some machine with plate mounting platform.

步驟二 (step 2)

3. 版材貼合 (Paste the plate)

使用橡膠滾筒貼版材增強結合力

避免氣泡的產生
To avoid bringing bubbles, please use a rubber roller to increase the linking force.

- 得到更高的壓力,將版材緊密貼合在膠帶上
- 使用手可能破壞精細網點,使用橡膠滾筒可得到更高的印刷效果
-Get a higher pressure, which paste the plate on tape tightly.
-Using hand may damage the exquisite net dot. Using rubber roller will get a higher printing effect.

步驟三 (step 3)

4. 防止溶劑接觸
Avoid touching solvent

在印刷時對版材的清潔應注意避免使溶劑接觸膠粘劑
The cleaning to plate should avoid solvent touching adhesive
避免翹版
Avoid plate warping

- 溶劑接觸膠帶會降低粘結力並導致翹版
- 可使用封版膠帶做永久或臨時封版以避免此現象發生
-Touching solvent will reduce the adhesion and cause plate warping.
-It can be avoid by using edge sealing tape.
.

步驟四 (step 4)

5. 卸      版 (Disconnect the plate)

以銳角緩慢而又平穩地將版材卸下 (小於 90°)
Disconnect the plate slowly and steadily by a angle less than 90°.
避免版材皺褶或破裂
Avoid wrinkle or break of the plate.

- 不要將版材和膠帶同時卸下
- 之後將兩者分離會非常困難
-Don't disconnect the plate and tape at one time.
-Or it will be very difficult to seperate them.

步驟五 (step 5)

6. 卸除膠帶 (Disconnect the tape)

最後以銳角平穩地將膠帶卸下 (低於 90°)
避免留下殘膠
Disconnect the tape steadily by a angle less than 90°, be care not leave residue.
