Paper surface chemistry as a tool to improve inkjet printing quality

The influence of paper surface sizing on inkjet

The effect of paper surface sizing on inkjet pigment penetration was evaluated by studying four different paper samples: one taken as reference, without surface sizing (paper RP), one surface sized with cationic starch (RPS1), one with a mixture of cationic starch and poly(styrene-co-maleic anhydride) (RPS2), and one with a mixture of cationic starch and poly(styreneco- acrylate) (RPS3). Assessment was based on...

Application of FT-IR-ATR Spectroscopy to Evaluate the Penetration of Surface Si...

It is widely recognized that the surface properties of paper depend on the fibrous matrix and the final surface treatment applied to the paper. Regarding chemical paper surface treatments, an important issue is the evaluation of the penetration of chemical compounds into the fibrous matrix, as the chemicals can potentially cause changes in the intrinsic properties of paper. The work presented here aimed to use ...

Effect of surface sizing on the surface chemistry of paper containing eucalyptu...

The effect of different surface sizing formulations on the chemical features of surfaces of the papers produced from Eucalyptus kraft pulp was studied. The surface analysis techniques, electron spectroscopy for chemical analysis and time-of-flight secondary ion mass spec- trometry were applied. An uncoated base paper, the ref- erence material, was sized with blends of cationic starch with either co-acrylonitril...

Evaluation of the Topography of Surface Sized Eucalyptus Based Papers

The surface properties of paper depend not only on the fibrous matrix but also on the final treatment of the paper surface. The present work compares paper samples with two different surface sizing treatments by using AFM and profilometry to assess topography and roughness parameters as well as to evaluate the spreading of the sizing formulation and to estimate sizing agent particle sizes. The results were conf...

Physical & chemical interactions on paper surface : impact on the printability ...

Actualmente assiste-se a uma crescente exigência dos consumidores relativamente à qualidade dos papéis de impressão e escrita (P&W), especialmente no que respeita à sua imprimabilidade. As interacções tinta-papel são afectadas quer pelas propriedades físicoquímicas da superfície do papel quer pelas propriedades da matriz fibrosa, pelo que não apenas o tratamento final da superfície mas, em geral, todas as opera...

Evaluating the surface energy of laboratory-made paper sheets by contact angle ...

Contact angle is one of the most useful tools to easily assess the surface energy of paper sheets. However, the results obtained should be treated with some caution, since these measurements are significantly influenced by the properties of the liquids used and of the paper surface. Our study compares the values of the contact angle and of the surface energy of laboratory handsheets produced with demineralized ...

Impact of surface sizing on inkjet printing quality

Printing quality is strongly influenced by the structural and chemical properties of paper surface, and is one of the most important factors concerning costumer’s evaluation. Thus, all studies regarding the evaluation of paper surface characteristics, the effects of surface treatments, paper-ink interactions as well as the influence of all these parameters on printing quality, are of utmost importance. The aim ...
