发现色彩的秘密—爱普生3LCD技术为商用用户打开新视界

在现代化商务办公中,投影机是办公室不可或缺的显示设备,广泛运用在IT、律所、广告公司等各行各业。一台好的投影机不仅能清晰地显示图表的黑白细节,更需要真实生动地还原文档色彩。不少读者来信反应有的投影机色彩表现黯淡,而有的投影机呈现的画面生动、自然。这是因为市面上主流的投影机采用3LCD和DLP成像技术,两种不同技术的色彩表现有所差异。今天,笔者就来分享几个设计行业的案例,为读者揭晓色彩亮度对于职场精英日常工作的重要性以及如何选择一台色彩真实自然的投影机。

1

从事设计工作的人们都知道,色彩的处理决定着一个作品的好坏。在工作中我们时常会使用投影机为客户演示各种各样的作品,比如一幅图画、一段影片、一个文档等,在这个过程中时常受到设计师们的困扰,明明设计的作品色彩是艳丽的,为什么投影机投放出来的效果偏差会那么大?

今天我们就来揭晓这个奥秘,众所周知投影机有一个核心的参数“亮度”,在购买投影机的时候商家们往往会告诉你设备的亮度是3000流明或者更高,这里通常指的是白光亮度输出,而如今采购投影机大家更看重的是另一个标准参数,那就是色彩亮度(CLO)。

2

色彩亮度(CLO)不仅能够让用户更好的了解投影机的效果,更对行业的蓬勃发展也有着强大的推动作用,早在2015年色彩亮度(CLO)被纳入工信部发布的《电子投影机测量方法(SJ/T11346-2015)》,同时也是工信部推荐的认证标准。

3LCD与CLO的完美结合

佟先生从事设计工作12年,每天除了创作还需要为客户讲解作品的想法,他告诉笔者,目前他们会议室安装了爱普生CB-X05投影机,色彩亮度为3300流明,在开着墙灯的情况下,CB-X05也能够很好的还原作品最真实的色彩。这里我们不得不提到爱普生3LCD技术,3LCD技术是色彩光输出的关键,采用3LCD投影机投出的图像,色彩还原为精准,极大满足了用户的使用需求。

在日常的商务会议中,演示PPT和WORD文档是最常见的,投影机最基本的要求是投影画面必须让会议室各个位置的人员都能清晰观看到图标、文字、图表等数据。上海某企业的张先生就告诉笔者,他们之前使用的投影机,半年后图像失真严重,画面上的文字变的模糊,严重影响到了工作。张先生所在的单位是装潢公司,在拿到客户的样板图后,他们需要为客户提供全景式的设计方案,然后为客户讲解设计的思路。但是在使用投影机演示的过程中,张先生发现客户所提出需求,采用淡绿色的背景墙偏色了,结果张先生只能让客户直接观看电脑中的效果图,这样才避免了一场尴尬。此事过后张先生经朋友推荐,购买采用3LCD技术的爱普生CB-U42投影机,它的色彩亮度(CLO)为3600流明,3LCD投影技术有效将光源分成红、绿、蓝三种颜色,通过其各自对应的分色镜再合成最终的画面,色彩没有丢失,是时时全彩呈像。输出色彩亮度与白色亮度相等的图像,则画面色彩表现更为真实。

3

在使用商务投影机的会议演示中,任何一点的颜色偏移或者不一致,即便再细微,都可能严重影响观看者的观看体验。因此,近些年以来,许多人在购买投影机时会特别关注色彩亮度(CLO)---这是一个备受瞩目的重要参数。

爱普生3LCD+CLO创造更多视界

一位资深广告人Linda告诉笔者:“不能把作品完美的呈现给用户是对创作者最大的伤害,直到遇见了3LCD投影机!”Linda表示,对于普通人而言,蓝色之间的色差或许并没有那么明显,但是对于连一个像素都不能放过的设计师而言,色差完全不能忍呢!另外,很多设计在展示时还可能出现色彩断层,色彩衔接不流畅的情况,严重影响效果的呈现,这样再美的作品也看不舒服。而爱普生3LCD投影机的色彩亮度(CLO)无论是在对精细色阶的还原能力还是在色彩汇聚上都要比其他技术更出色。尤其是在对文字、图像、影像、色彩复杂的设计作品进行展示时,不会出现重影、毛刺、失真等现象。是设计作品真实呈现的一大利器!

4

很多时候大家或许都有这样的一个疑问,为什么同样的一个作品在不同的投影机投放效果差别会那么大,有的灰度严重有的色彩失真或偏色,这其实就是投影机色彩亮度低造成,市场上有些品牌仅披露白色亮度却隐瞒色彩亮度,不可避免地误导了消费者作出错误的决定。

我们都知道投影机最重要的参数之一就是亮度,更有一些行业人士表示选投影就是选亮度,而许多单位对亮度的检测方法,只是检测投影机投到屏幕上的光值,这就是白光亮度,而如今投影机所演示的作品更多是彩色的,因此以前的测试方法到今天是不够科学的。而色彩亮度(CLO)的标准是用来测量色彩的光输出情况,测试投影机的色彩表现,所以越来越多的行业用户以此标准作为投影机的参数指标。

如今,作为投影显示行业的标准,色彩亮度标准化在业界得到广泛应用。只有当白色亮度等于色彩亮度时,投影机才可能呈现真实明艳的色彩。色彩亮度的重要性不应该仅仅掌握在业内人士手里,更应该是用户在选购时的必备法则。
