Print by Number:: Fogra PSO to G7 on Curve 2
有機會操作到 Curve 2軟體，將我們依照Fogra PSO設定的印刷品丟到 Curve2軟體，看看是什麼結果。
Printer: Heidelberg CX 102
RIP: TrueFlow (依Fogra PSO 曲線出版)
量測工具組合: Xrite Colorport with i1iO (sn 879289 w/UV cut)
(ps. 本次數據含UV cut, UV cut 問題於後面說明)
1. Curve 2 內定 Target 為 Gracol 2006 coated，非 ISO Coated V2(eci)。
2. 經由Curve 2 判定，本次印刷油墨及紙張均符合 Gracol 2006 coated(G7)。經比對 ISO Coated V2(eci) 及 Gracol 2006 Coated 的data set，油墨及紙張的定義是一樣的。

3. 經由Curve 2 判定，目前設定(依Fogra PSO)，灰色平衡已達標準，K curve 已達標準，CMY curve Max wdL* 稍大一些(3.11 on 3.0)
4. Curve 2軟體與Fangraph paper 方式回應的修正數據約有兩個 網點 的差距，參考下圖

Curve2 K 修正: 
Fangraph CMY修正:
Curve 2 CMY修正: 
5. 關於 UV cut 及 i1iSiS 問題，我直接詢問亞洲區總部(香港)，重點如下；
======================================================================
1. Does it needs UV cut or not?
If for G7 Master qualification, no UV cut is used.
2. Does it have to restrict to i1ISIS? Could I use i1IO?
If for G7 Master qualification, we only accept the IT8 readable by i1ISIS because we will use i1ISIS for verifying the press form. This rule is set by IDEAlliance, so we follow it. But in future, we may also use i1IO as well.
==============================================================================
1. 香港確定不能使用 UV cut.
2. 目前必須使用 i1iSiS,但以後有可能可以用 i1IO。
=======================================================================
