pica是一种排版计量单位,通常用于测量字体线条。一个皮卡等于12点,一英寸有6个皮卡。许多数字平面设计师在他们的作品中使用英寸作为衡量标准,但在印刷工、排版工和商业印刷商中,picas和points仍然有很多追随者。
在18世纪和19世纪,一个点和一个异教徒的大小各不相同。然而,美国使用的标准是1886年制定的。美国的picas和PostScript或计算机picas的尺寸为0.166英寸。这是现代平面设计和页面布局软件中使用的pica度量。
通常,PICA用于测量列和边距的宽度和深度。点用于测量页面上较小的元素,如类型和前导。由于大多数报纸仍然使用picas和points,您可能需要为您的日报准备picas和points广告。
在Adobe InDesign和Quark Express等页面布局软件中,字母p与数字一起使用时表示PICA,如在22p或6p中。如果给pica加12分,半个pica等于6分,写为0p6。17个点写为1p5(1个pica=12个点,加上剩余的5个点)。同样的页面布局程序也为那些不想在Pica和points中工作的人提供英寸和其他尺寸(厘米和毫米,有人吗?)。软件中测量单位之间的转换很快。
在web的CSS中,pica的缩写是pc。
1英寸=6便士
1/2英寸=3p
1/4英寸=1p6(1个异径点和6个点)
1/8英寸=0p9(零PICA和9点)
2.25英寸宽的文本列为13p6宽(13个Pica和6个点)
1点=1/72英寸
1皮卡=1/6英寸
如果您对一个测量系统感到满意,则无需立即进行更改。已经存在一段时间的平面艺术家和排版师都在其中钻研了pica和point系统。对他们来说,用毕加索画法和用英寸画法一样容易。报业从业人员也是如此。
有些人认为PICA更容易使用,因为它是一个“基数12”系统,很容易被4、3、2和6除。有些人不喜欢使用小数,因为1点实际上等于0.996264英寸。
与各种客户合作的图形艺术家会发现,有些人使用英寸,有些人使用picas,因此对这两种系统的基本了解非常有用。
