New Print feature in PCD7.0.6

Question

New Printing feature for Layer Opacity? Attributes (transparency).

Requirements

PowerCADD 7.0.6 and Mac OS? X Tiger or Leopard (10.5.2 or newer recommended)



Background

Engineered Software issued an update to PowerCADD 7 bring it up to 7.0.6 as we noted in this article. As part of that general update, there is new feature related to printing of drawings using Layer Opacity settings other than 100%. Adjusting the Layer Opacity is a common technique to reduce the visual impact of content and help increase readability of drawings. However, in the Postscript printing world, transparency effects require the image to be flattened and rasterized (converted to pixels) which can lead to artifacts or a fuzzy looking image for all objects, on all layers, which might overlap with the transparent objects.

This article briefly describes that new feature and how it's intended to help address that printing condition.

What To Do

Choosing File? menu > Print..., then choosing PowerCADD Options opens the dialog pictured above.

Gray Pattern for Dimmed or Transparent Layers is an application wide setting to help address Postscript and PDF? workflows and flattening of transparent objects. Due to limitations in how transparent content is flattened (rasterized) at the operating system level during the Postscript and PDF printing process, the output may appear to become fuzzy or less sharp.

When checked On (enabled) the WYSIWYG? relationship between screen display and printed output is affected for objects with a Dimmed layer status or objects residing on layers with a Layer Opacity setting other than 100%. Filled patterns are not printed, and text, bitmaps and placed objects are printed as if their opacity were 100% (solid); objects on these layers are printed with a gray pen pattern instead. Settings applied for Color printing options in Drawing Setup, Print tab still apply.

When unchecked (off or disabled) the transparency setting set when a layer status is Dimmed or Layer Opacity settings are changed will be applied to all objects when rendered to screen and when printed. In the case of non-postscript printers, leaving this box unchecked (off) is recommended to maintain the WYSIWYG relationship between the screen display and printed output.

We hope that helps
