![]() ![]() They blend easily, produce consistent color, and dry quickly. Markers labeled as alcohol based are often intended for art. Given these similarities, what a particular pen is called has more to do with what the manufacturer wants to emphasize about its characteristics than an actual distinction in its composition. They may also have a strong smell that makes them unpleasant to use for long periods. The counterpoint to this benefit is that the oil- and alcohol-based inks used in markers spread out on regular paper, making wide lines that are hard to control. They are also able to write on slick surfaces better and with a more reasonable drying time than water-based inks. They may be colored with dyes or pigments and are typically water resistant or waterproof. ![]() In general, oil- and alcohol-based pens contain both alcohols and oils. Despite all the complexity and variability that the other elements of the ink introduce, this information gives us valuable clues about how the ink is likely to behave.Īlthough they’re spoken of as distinct categories, there are no consistent differences between oil-based and alcohol-based inks either chemically or in terms of their performance. We do, however, usually know the two basic components of the ink: the vehicle and the colorant. Ink manufacturers are extremely protective of their proprietary formulas, so we aren’t able to use the specifics of their ingredients or mixing processes to inform our ink choices. Just like bread and pizza dough contain similar ingredients but turn out differently when baked, inks made with similar components can have different characteristics depending on how they are treated during the mixing process. These ingredients are then combined in a specific way to ensure that the ink has the correct characteristics. For example, manufacturers may use surfactants to give an ink the right surface tension to flow reliably through a pen, binders to help deposited color stick to the paper once the vehicle evaporates, and preservatives to prevent mold. Inks also contain several additives that fine-tune their performance. See our Glossary for more information.įundamentally, all inks are made of color that is dissolved or suspended in a vehicle (also called a solvent or carrying medium) that delivers that color to the paper. *There is no standard definition of what “permanent” or “archival” means for an ink.

Results were best with Method 3 followed by Method 1 and 2, respectively.Īcrylic colours have more advantages compared to India ink. Shade #09 showed loss of colour and the shade #23 showed penetration into deeper tissues on microscopy. Shades #64, #18, #09, #23 had poor microscopic visibility in all three methods. Coloured inks were assessed on different parameters for their performance as surgical ink and given scores.Īcrylic shades #04, #22, #06, #01, #02 and India ink had very good to excellent score on microscopy in all three methods. The following day, it was re-coloured with the same colours as of the previous day and subsequently sections were taken. In Method 3, the specimen was inked and kept for overnight fixation. In Method 2, the specimen was inked and kept for overnight fixation. In Method 1, coloured inks were applied to an overnight formalin fixed specimen and representative sections were taken. Thirteen acrylic colours along with India ink were evaluated via three different methods on radical specimens of breast and colon after preliminary requisites of grossing were completed. The present study was undertaken to analyse acrylic colours and Indian ink for inking surgical margins via three different methods for optimum results. On other hand acrylic colours, available in variety of colours can be used for inking multiple margins along with many more advantages. India ink has long been used but it can ink only one margin. Proper identification of surgical margins along with margin status holds utmost importance in histopathology. ![]()
