【CPP114】讯：最近印艺月刊人事变动，新的编辑上场，仍在摸索阶段，要逐步适应月刊风格，一些技术性栏目需要联络不同作者和专家，对新上任的编辑来说确不容易。其实自去年编委会定下的两个论坛议题中，「印刷色彩表现」发表的文章较多，讨论范围比较广泛，但是仍然未能达到笔者的期望，而事实上仍有多位专家学者抱观望态度，未有对此议题表态。


　　印艺月刊过去所发表之《三地书柬》，最多学者专家参与讨论的题目便是「印刷名词的规范」，当年笔者建议集中精力规范新生词，比重新规范三地已应用流通多年的旧名词更为有效和实际，所以三地论坛中另一公开议题便是「印刷新生词」，很奇怪三地学者专家反应却很冷淡，为此笔者将一些近年常见的印刷媒体新生词分期列出，就教三地高明，希望藉此引起各位参与论辩。


　　1. Adjacent colors — Adjacent colors, also called analogous colors refers to the use of compatible color combinations that blend well together and are near each other on the color wheel (e.g. yellow, to yellow orange, to orange). These colors are more subdued and are not bright vivid colors.


　　英文原文大意是两个颜色之邻接位较弱之颜色，例如由黄至橙之间的黄橙渐变色。个人将此名词中译为──淡接色。


　　2. Alpha channel — In graphics, a portion of each pixel‘s data that is reserved for transparency information. 32-bit graphics systems contain four channels — three 8-bit channels for red, green, and blue (RGB) and one 8-bit alpha channel. The alpha channel is really a mask — it specifi es how the pixel‘s colors should be merged with another pixel when the two are overlaid, one on top of the other.
Typically, you wouldn‘t defi ne the alpha channel on a pixel-by-pixel basis, but rather per object. Different parts of the object would have different levels of transparency depending on how much you wanted the background to show through. This allows you to create rectangular objects that appear as if they are irregular in shape — you defi ne the rectangular edges as transparent so that the background shows through. This is especially important for animation, where the background changes from one frame to the next.

　　英文原文大意是类似图像遮盖由深至浅的透明变化使背景颜色显示出来。


　　笔者认为应将此名词中译为──迭像透现。

　　3. Alpha blending — Rendering overlapping objects that include an alpha value. In computer graphics, combining the → alpha channel with other layers in an image to show transparency. More than one layer in a multi layered image may contain a translucent component, thus multiple levels of blending may be required. If the graphics accelerator performs the blending in its own hardware, the results are displayed considerably faster.


　　英文原文大意是重迭图像的混合透明变化使背景不同程度显现出来。


　　笔者认为应将此名词中译为──混迭透现。


　　4. Burner — Slang term for an internally or externally driven device for recording data on blank CDs or DVDs. The laser beam creates minute, precisely defi ned pits in the surface which represent 0 in binary computing. The non-lasered areas, known as lands, resent 1s. The reading head distinguishes between the lands and pits based on the amount of scattering or defl ection that occurs when the beam of light hits the surface of the disc. Deviations in pit dimensions can cause reading errors.


　　英文原文大意是内置或外置、可将数据信息抄录在空白的 CD 或 DVD 上的器材。


　　个人将此名词中译为──烧录器。


　　5. CTF – Computer to film. Term used to describe the transfer of pre-press data onto fi lm via an LED/laser imagesetter, with no manual steps in between. The imaged film can contain one or more pages of text and / or pictures.


　　英文原文大意是将印前数据通过 LED 或激光成像机，将文字及影像制成胶片。


　　笔者认为应将此名词中译为──计算机制片。


　　6. CTP – Computer to plate. Term used to describe the transfer of prepress data directly onto the plate via on-press IR, UV or violet laser imaging, eliminating the intermediate steps of conventional film imaging and stripping.


　　英文原文大意是将印前数据通过红内线、紫外线或紫激光将文字及影像直接制成印刷版。


　　个人将此名词中译为──计算机制版。


　　注：CTP 也有称为 Computer to Paper，即直接将印前数据在纸上印出来，其实便是数码印刷 Digital Printing。为免混淆，建议CTP 只用于Computer to Plate.
