Specialty paper is widely used in corporate book printing to enhance brand image and convey premium quality. However, due to its unique characteristics, printing on specialty paper requires greater attention compared to standard paper.
Surface Texture and Grain Direction
When using textured specialty papers, it is crucial to align the grain direction with the binding orientation of the publication to prevent cracking or warping. Optimal cutting methods should be employed to balance cost efficiency with aesthetic outcomes. Papers with pronounced textures may cause uneven ink adhesion, potentially resulting in slight ink leakage along surface lines during printing. Additionally, highly textured or irregular surfaces may not be suitable for high-resolution halftone printing due to dot gain and loss of detail.
Domestic vs. Imported Pearlescent Paper
There are notable differences in print performance between domestic and imported pearlescent papers. Domestic varieties often exhibit inferior ink receptivity, leading to duller printed results. In contrast, imported pearlescent papers generally provide superior color vibrancy and consistency. For projects requiring high color fidelity-such as fashion catalogs-it is advisable to use imported materials. However, for less demanding applications, domestic options may suffice depending on design specifications and client expectations, particularly considering the significant cost difference.
Ink Selection and Application
Specialty papers with smooth surfaces-such as pearlescent, ice-white, or high-gloss finishes-typically have low ink absorption rates. To prevent set-off (ink transfer to adjacent sheets) and staining, quick-drying inks supplemented with drying agents are recommended. Ink coverage should be moderate; over-inking increases the risk of offsetting, especially on non-porous surfaces.
Conversely, rough-textured papers-including handmade paper, kraft paper, writing paper, and certain coated stocks-possess higher porosity and better ink absorption. As ink penetrates into the surface texture and fibers, dried prints may appear lighter than expected, compromising color accuracy and visual impact. Therefore, increased ink feed and higher saturation settings are necessary to compensate for this effect and ensure satisfactory print quality.
Test Runs and Process Control
Due to the high cost of specialty paper, material allowances are typically minimal. Each time the press stops and restarts, mechanical vibrations can cause initial impressions (approximately the first 10 sheets) to appear darker, leading to inconsistent color output. This issue is particularly pronounced in gravure printing, where frequent interruptions result in substantial waste. Given the elevated technical demands, adherence to standard operating procedures is insufficient. Comprehensive test runs are essential to calibrate equipment, verify color stability, and ensure both quantity and quality meet required standards before full-scale production begins.
Dry
The ink absorption properties of different special papers vary. Smooth-surfaced papers are difficult to dry and must be left for a longer period of time. They should be inspected after drying to avoid backside smudging. Special paper printing is not an easy task. Before printing, one must be meticulous and control all aspects carefully to ensure the smooth progress of the printing process.
