Fluorescent ink

螢光油墨 / Fluorescent ink

包裝中的樣本是專為巴黎藝術機構CentQuatre提供的2014/2015年計畫,封底紙張採用Curious Metallics Ice Silver 120g,呈現四種螢光油墨,內頁採用Olin Rough High White 80g。

The enclosed sample is the 2014/2015 programme for the CentQuatre, an artistic establishment in Paris. The cover is printed on Curious Metallics Ice Silver 120g and showcases 4 different fluorescent inks. The inside pages are printed on Olin Rough High White 80g.



  • 使用少量或不含螢光增白劑的紙張,例如Rives Natural White 或 Conqueror Bamboo Natural White,以充分凸顯螢光油墨的效果。
  • 請使用螢光油墨打印擁有大面積純色區中的淺色或亮色圖像,螢光黃和洋紅最佳,藍色欠佳,螢光油墨還具有快乾優勢。
  • 衡量所用紙張與螢光油墨之間的對比度,例如用螢光油墨打印Conqueror Laid 或 Conqueror Connoisseur等傳統紙張會產生特殊的反差效果。
  • 選擇圖片中準備印刷螢光油墨的區域,添加五號色作為印刷螢光油墨的重點區域,同時確保其他顏色不被破壞。
  • 網版印刷對圖像的耐用度、不透明度和持久度要求較高,請謹慎考慮使用的螢光油墨。


  • 陰影較多的深色圖像不適合使用螢光油墨,會破壞原有的字體粗細度和顏色對比度。
  • 雷射雕刻機或辦公事務機所用的紙張不適合螢光油墨印刷,螢光油墨不耐高溫。
  • 螢光油墨褪色快,需避免陽光照射,因此較適合使用期限短且視覺效果強烈的宣傳印刷品。
  • 此類油墨透明度高,需兩次印刷,且印刷基底上的螢光增白劑會影響最終印刷效果。
  • 請勿在螢光油墨上塗抹防護層,水性或油性光油都會減弱此油墨的螢光性。


The pigments in fluorescent inks work by absorbing ultraviolet energy (invisible to the human eye) and transmitting it as longer waves in the visible spectrum.

  • DO use uncoated UV dull papers – with low or no fluorescence such as Rives Natural White or Conqueror Bamboo Natural White – to emphasise the fluorescent inks to full effect.
  • DO use fluorescent inks when printing light and bright images with large, solid areas. Fluorescent yellow and magenta provide the most impact, while blues are less effective. Fluorescent inks also have the advantage of fast drying time.
  • DO play with contrasts between the paper used and fluorescent ink. Printing a classic paper like Conqueror Laid or Conqueror Connoisseur with fluorescent ink will add a touch of modernity and create eye-catching communications.
  • DO choose where the fluorescent ink prints on the sheet, keeping other colours true such as flesh tones, by adding a fifth colour to integrate the fluorescent ink exactly where you want as a highlighted area. This will provide extra control and more impact on a press.
  • DO consider fluorescent inks printed by the screening process were more durable, opaque, long lasting images are required.

Uncoated papers tend to soak up the ink, lessening the brightness of the printed images. One way around this problem is to substitute fluorescent process inks for traditional process inks. The printed effect is to add a luminescence to the image. The less fluorescent ink you use, though, the more subtle the radiance is.

  • DON’T use fluorescent ink in dark images with a lot of shadows, you can potentially lose weight and contrast.
  • DON’T use fluorescent ink for stationery that will be run through a laser printer or copier for fluorescent inks are not formulated to resist high heat.
  • DON’T overlook the limitations of fluorescent inks; that is, they fade quickly and need to be kept out of direct sunlight, which is why they are best suited for high-impact promotions with a short shelf life. In addition, they are very transparent and may require a double pass on press. Note that the amount of optical brighteners used in the substrate to be printed on will have an impact on the final result.
  • DON’T apply coatings on fluorescent inks. Aqueous coatings can cause them to “burn out” so that they fade more quickly than when a varnish is applied. In either case, however, the coating may slightly decrease the fluorescent effect.
