For photographers who print their own work.
To reach what the printer was truly capable of.
为亲手打印作品的摄影师而做。
追到打印机本该抵达的色域边界。
A modern 12-ink printer can reproduce a breathtaking gamut. Most of the time, you never see it.
Between the image you saw on your screen and the drops that land on paper, there is a stack of layers translating your colour — and each layer, if not held accountable, will quietly compress, clip, or second-guess you.
一台现代 12 色打印机，能重现的色域令人惊叹。大多数时候，你从未见过它。
在你屏幕上的画面和落在纸上的墨之间，夹着一层层系统在替你翻译颜色 —— 任何一层没被看管，都会悄悄压缩、截断、或者替你猜一个"差不多"的答案。
The system and the driver both think they are in charge. They aren't. The image pays for it.
系统与驱动都以为自己在管颜色，其实谁都没管好。买单的是画面。
A 16-bit file goes in, an 8-bit tonal step comes out. We keep it 16-bit all the way.
输入的是 16 位文件，中途被截成 8 位阶梯。我们让它 16 位走到底。
Monochromes quietly turning warm or cold under different light. We address it with two black-ink workflows, chosen on purpose.
黑白照在不同光下悄悄偏暖偏冷。我们用两套刻意挑选的黑墨工作流应对它。
An OS update, and yesterday's paper setting is gone. We keep them inside jcolour, where you put them.
一次系统升级，昨天调好的纸张设定不见了。我们把它们放在 jcolour 里，你放在哪就在哪。
Talk to Epson UltraChrome P-series without the middleman. 16-bit end-to-end. No OS sleight-of-hand.
绕开中间层，直接与 Epson UltraChrome P 系列对话。16 位全链路，不被系统偷偷改手脚。
Each ink behaves differently on each paper. jcolour measures, fits, and lets you nudge — PK, MK, LK, LLK, all of them.
每支墨在每张纸上都有自己的脾气。jcolour 会测、会拟合、也允许你亲手微调 —— PK、MK、LK、LLK，一支不落。
Single-black for archival carbon purity. Multi-channel black for split-tone and dimensional monochromes. Chosen explicitly, not by accident.
单黑模式 —— 纯碳黑，档案级。多色黑模式 —— 可做三段分色调，还原立体的黑白层次。由你主动选择，不是默认。
Paper white simulation, ΔE heat-map, intent suggestion, BPC preview. An honest screen before the ink runs.
纸白模拟、ΔE 热力图、渲染意图建议、BPC 开关对比。让屏幕在开印前先说真话。
Paper × profile × ink × settings, bundled as one. Named. Versioned. Lives inside jcolour, not the system dialog.
纸张、ICC、墨型、参数打包为一个预设。命名、版本、存在 jcolour 里，不被系统对话框吞掉。
Limited-edition numbering, ink-batch log, re-print continuity. Because archival means the next print looks like the last.
限量版编号、墨批次记录、重印一致性追踪。所谓"档案级"，就是五年后重印，看起来还是同一张。
We are looking for twenty photographers who print their own work on Epson P-series. You bring the hardware, the paper, and the opinions. We bring jcolour, an email thread, and fast fixes.
Write to us. Tell us what you print, what paper you live on, and what colour has been evading you.
jcolour@qq.com我们在找二十位亲手打印作品、使用 Epson P 系列的摄影师。你带上硬件、纸张和意见，我们带上 jcolour、一条邮件线索、和尽快的修复节奏。
写信给我们，告诉我们你在打什么、常年用哪种纸、哪个颜色一直追不上。
