Once you choose your resume paper, select an ink color. Avoid wild colors and mixing multiple colors. Black ink is the most popular and most traditional color. If you choose to print your resume using an alternate color ink, make sure your selection is professional looking. Brown or burgundy are good alternatives. Make sure the ink color and the paper you choose don t clash. Also, make sure the text is easily readable both to the human eye and to computer scanners. If faxing your resume to employers, your paper and ink color selections should be white paper with black ink. If your resume is difficult to read, people won t read it. 

While collecting and using this particulate matter to study the textile as a whole may be useful, it cannot totally replace direct sampling because particulate cannot be associated directly with particular areas of the textile. It is also possible that the particulate is contaminated with material that is not from the textile. Therefore, when studying coloration, selective sampling of particular colors or areas with different chemical signatures will still need to be done. Thereby, materials of different composition or color are kept separated and each can be analyzed by itself. 

To merge. kin files, select Append File tool of the File menu and open the hie to merge. To change default color, invoke Change Color tool of the Edit menu and click the structure element to open Color selection box from which the desired color can be assigned. Different structure views are created/added to the. kin hie by selecting Keep Current View tool of the Edit menu and entering View number and... 

The interior surfaces of the skylight windows of the Technical Library in the Research Building are covered with 3M Scotchtint Solar Control Film, attached at the top and bottom by rods. This screening material is made of a flexible polyester film of 15/1000" total thickness and is aluminum vapor coated. The color selected was smoke (grey black) and,... 

The object is the second part of our triad. Here we will discuss how materials interact with the energy from the light source. In this book we consider objects made of polymeric materials. Generally, polymers are colorless or at best weakly colored, and the aim always seems to be to cover up the undesirable color of the polymer in favor of the more desirable color selected by the designers. This requires the addition of colorants (pigments and dyes) to the polymer. The subject of colorants will be covered in depth in another chapter. However, because colorants become part of the object, we will first discuss some aspects of how they interact with light. 

End-use stability and performance are the net result of good design and colorant selection. In the case of colorants, end-use stability and performance most often refer to ability to resist attack by chemicals, solvents, heat, weather, and gases and aerosols found in the product environment. The resistance of a plastic product to attack by any of these in a laboratory can produce definitive results. In combination, these elements are difficult to quantify not only in the laboratory but also in actual exposure to them. Thus, testing throughout a project from start to finish is vital to the technical and commercial success of that plastic product. In this chapter the focus is on the role the colorants play in the success. 

Colorant systems are available in several forms, and it is a good idea at this juncture to establish with the customer the method they prefer to use to introduce color into their molded or extruded part. Colorant system form may have an influence on colorant selection and will influence additives and binder selection. Colorant systems are available in the following forms ... 

Colorant selection is the most difficult step in the color-matching process. There are hundreds of pigments and dyes to select from and the trained colorist should be... 

The reader should learn as much as possible about the properties of colorants and polymers as well as about plastics processing and plastics applications. Colorant selection is the hard part. Color matching is easy. 

More recently, a spirobenzopyran dimer bridged by a diaza-18-crown-6 moiety through the 8-position (67) was developed by Kimura and co-workers.119 121 Crowned bis(spirobenzopyran) 67 shows a similar coloration selectivity to that of 63. Complexation of multivalent metals, especially Ca2+ and La3, by 67 enhanced the isomerization of the spirobenzopyran moiety to the corresponding merocyanine form due to an effective intramolecular interaction between a crown-complexed cation and the two phenolate anions in the cation complexes of the merocyanine form. 

Colorants and opacifiers are typically used at low concentrations in the wet gel formulation. A wide range of colorants such as FD C and D C water-soluble dyes, certified lakes, pigments, and vegetable colors have been incorporated into Softgel shells alone or in combination to produce the desired color, tint, or hue for product identification. A general rule in color selection is that the color of the capsule shell should be similar to or darker than the fill material to reduce the contrast with the seams.
