    • A graph paper is provided that is adapted to prevent transfer of construction lines from an original sheet to a copied sheet when using a photocopier or scanner. The graph paper comprises one or more sheets having grid lines in a grid pattern thereon. The lines are printed such that they comprise a similar grayscale value with respect to the page grayscale color. The difference between grid line grayscale value and the page grayscale value are such that a photocopy machine or a scanner will not readily register the lines when transferring the images of the page, and therefore will not readily transfer the grid pattern from the original page to a copy or reproduced image. The graph paper is therefore adapted for use when taking hand calculations or notes by hand, whereafter the writing can be reproduced without the clutter of the grid lines being transferred when copied or scanned.
    • 提供了一种图形纸,其适于在使用复印机或扫描仪时防止施工线从原始片材转移到复制的片材。 图形纸包括一个或多个具有栅格图案的网格线的片材。 这些行被打印,使得它们相对于页面灰度颜色包括相似的灰度值。 网格灰度值与页面灰度值之间的差异使得复印机或扫描仪在传送页面的图像时不会轻易注册线条,因此不容易将网格图案从原始页面转移到 复制或复制图像。 因此,图形纸适用于手动手动计算或笔记时使用,此后可复制写入,而不会在复制或扫描时传输网格线的杂乱。
