Water-based UV-curable prepolymers are novel environmentally friendly materials. The blending property of two kinds of the prepolymers, water-based UV-curable polyurethane acrylate (UVPU) and water-based UV-curable epoxy acrylate (WEA), was studied in this paper. Blending compatibility, curing rate, optical and mechanical properties, and the cross-section morphology of the cured films of UVPU and WEA were investigated by Fourier transform infrared (FTIR), UV-visible spectrophotometer (UV-vis) and Environmental scanning electron microscopy (ESEM). Results indicated that the two prepolymers had good blending compatibility and high curing rate under UV radiation. The elongation at break of the cured film by WEA mixed with 20 wt% UVPU had 1.5 times increase compared to pure WEA, and the gloss increased 23% compared to pure UVPU, but the tensile strength decreased slightly. The morphology showed that the molecules of the two prepolymers polymerized each other and formed a network similar to the structure of Interpenetrating Polymer Networks (IPN). The comprehensive properties of the film were improved by blending of WEA and UVPU, and could be widely applied in the fields of coating varnish or printing ink.

This paper is to study factors that affect soaping color fastness of inkjet printing ink. Considering ink as a constant, discuss the affect of curing conditions on soaping fastness by altering curing temperature and curing time. Considering curing condition as a constant, study the affect of other factors on soaping fastness of ink, like particle size, the binder content and varieties of binder. The results show that: the soaping fastness is better when the curing temperature is 180°Cand curing time is 3minites; The smaller the particle size of ink is, the higher the soaping fastness is; the soaping fastness is well when the binder content of ink accounts for 20% of the total. The water-based polyacrylate and water-based polyurethane have the same effects on soaping fastness.

The performances of three kinds of water-based pigment inks were compared and studied, which include self-made ink, original printing ink and compatible ink. Art paper, matte paper and white card paper were used as the substrates. Testing the contact angle of ink droplets, the spreading, wetting, and drying rate of inks were investigated. The color density and CIE L*a*b* values of the printed samples were measured, to evaluate the hue error and color gamut. The water resistance was studied with corresponding experiments. The result indicates: self-made water-based pigment ink has the smallest contact angle on coated paper, showing a faster drying rate. Its color gamut is similar to the original printing ink on art paper, and the hue error is low. Through the water resistance test, the color density measured on art paper and matte paper had no changes, without color dissolving and color fading, showing good water resistance applicability.

Abstract In the present study, near-infrared sensors are used to investigate moisture variations on paper in the heatset web offset printing process. The moisture content was determined from both non-image and image printed areas at multiple locations along the printing line. The amount of water based liquid (fountain solution) transferred to the two studied areas as well as the internal moisture content of the paper was investigated in terms of near-infrared absorbance response. In order to achieve absolute moisture content estimates, the sensors were calibrated for the respective measurement regions. It was found that the moisture content was higher in the areas with printing ink compared to those without. The heatset drying had a stronger moisture drying effect on the non-image areas. The tests were performed in both a laboratory and a full-scale heatset offset printing environment.

This paper is to determine the effects of various factors on the color fastness to crocking of inkjet printing ink. Firstly, the affects of curing conditions on color fastness to crocking were discussed by altering curing temperature and curing time separately. Secondly, considering curing conditions as a constant, study the affects of the pH of ink, the amount of adhesives and the varieties of adhesives on color fastness to crocking by changing these factors respectively. The results show that: the color fastness to crocking of printing fabric is better when curing temperature is 1800C and curing time is 90s; the wet crocking fastness of printing fabric declined as the pH of ink increased; the color fastness to crocking of fabric printed with ink which prepared use water-based polyurethane is better than use water-based polyacrylate.
