PROBLEM TO BE SOLVED: To provide a data generation method that can simultaneously obtain data for an etching resist and prediction data of a finish circuit pattern and is excellent also in having simple generation process and versatility.SOLUTION: A method of generating data for an etching resist for a printed wiring board and prediction data of a finish circuit pattern, in which an outside virtual line formed by combining points on a circumference of circles distanced most outside in a direction orthogonal to a partial line part of a target contour data connecting centers of circles having an apex of target contour data formed by combining many apexes as a center and an inside virtual line formed by combining points distanced in most inside are acquired, data for the etching resist are generated using the outside virtual line, and prediction data of the finish circuit pattern is generated using the inside virtual line.SELECTED DRAWING: Figure 1 【課題】エッチングレジスト用データ及び仕上がり回路パターンの予測データを同時に得ることができ、生成過程がシンプルで汎用性にも優れるデータ生成方法の提供。【解決手段】プリント配線板用のエッチングレジスト用データ及び仕上がり回路パターンの予測データを生成する方法であって、多数の頂点を結んで形成される目標輪郭データの前記頂点を中心とした円の中心同士を結ぶ前記目標輪郭データの各部分線分と直交する方向にして最も外側に離れた前記円の円周上の点同士を結んで形成される外側仮想線と、最も内側に離れた点同士を結んで形成される内側仮想線とを取得し、前記外側仮想線を用いてエッチングレジスト用データを生成し、前記内側仮想線を用いて仕上がり回路パターンの予測データを生成する。【選択図】図１
