历史普鲁士蓝（PB）颜料作为不溶性沉淀物以定量产率从Fe 3+和[Fe-II（CN）（6）]（4）-（Fe 2+和[Fe-III（CN）（6）]（3-））的水性混合物中容易地获得。已经发现，基于粉末X射线衍射（XRD）线加宽和透射电子显微镜（TEM）图像，PB颜料固有地是10-20 nm纳米颗粒的附聚物。PB颜料已作为有机溶剂可溶性和水溶性纳米颗粒油墨而复兴。通过用脂肪胺对纳米粒子进行表面改性，使纳米粒子从不溶性团聚体中稳定地分散到常用的有机溶剂中，得到透明的蓝色溶液。用[Fe（CN）（6）]（4）-进行相同的修饰产生水溶性PB纳米颗粒。类似的油墨制备适用于Ni-PBA和Co-PBA（六氰基铁酸镍和钴）。PB（蓝色）、Ni-PBA（黄色）和Co-PBA（红色）纳米颗粒用作三原色油墨。
Historic Prussian blue (PB) pigment is easily obtained as an insoluble precipitate in quantitative yield from an aqueous mixture of Fe3+ and [Fe-II(CN)(6)](4)-(Fe2+ and [Fe-III(CN)(6)](3-)). It has been found that the PB pigment is inherently an agglomerate of 10-20 nm nanoparticles, based on powder x-ray diffraction (XRD) line broadenings and transmission electron microscopy (TEM) images. The PB pigment has been revived as both organic-solvent-soluble and water-soluble nanoparticle inks. Through crystal surface modification with aliphatic amines, the nanoparticles are stably dispersed from the insoluble agglomerate into usual organic solvents to afford a transparent blue solution. Identical modification with [Fe(CN)(6)](4)-yields water-soluble PB nanoparticles. A similar ink preparation is applicable to Ni-PBA and Co-PBA (nickel and cobalt hexacyanoferrates). The PB (blue), Ni-PBA (yellow), and Co-PBA (red) nanoparticles function as three primary colour inks.
