With the development of fluorescent technology, the application area of fluorescent material is expanding, which includes the fields of traffic, national defence, architecture, detection, decoration etc. In the field of printing, whether in the value of utility or view and admire, fluorescent adds tremendous energies. However, a majority of fluorescent materials used nowadays contain radioelement, which will do harm to human health. This paper considers the needs of fluorescent map printing, according to the defects of traditional fluorescent material such as low brightness, short duration time, strong radioactivity, limitation to spot color printing etc. It improves the capability of long fluorescent lag material and makes red, blue, green and yellow long fluorescent lag materials. Meanwhile, it tests the influence of ink thickness, illumination time and granule size etc. on irradiance capability. The thicker the ink is, the longer of the lag time will be. The bigger the granule size is, the lag time will be. It also tests its radioactivity extent, which is in the safety range and reaches the standard of environmental protection. According to the special requirement of map printing, this paper brings forward the technique scheme of the application of long fluorescent lag ink in map printing,which realizes the color fluorescent map printing.

Fluorescence increased during storage in defatted, dried egg powders, and also in separately dried yolk and white. A portion of the fluorescent material was soluble in fat solvents and especially in alcohols. Ethanol may also destroy some of the fluorescing substance. The results indicate that fluorescent materials arise from changes in the protein fraction, that there is more than one fluorescing substance, and that some of these materials contribute to the increased fluorescence associated with decrease in quality. Indirect evidence indicates that proteose and peptone constituents are partly responsible for fluorescence, and that the nature of the deterioration is hydrolytic. A preliminary study was made of the effect of certain enzymes and micro-organisms on the formation of fluorescent materials. The work is being continued.

The article reveals a number of rules regulating the arrangement of a series of two-dimensional images universal both for works of fine art, as well as photography and design. The authors outline the key principles of creating such a series through a thorough description of the working process behind “The Herbs”, a set of five etchings by Elena Grazhevskaya. The aforementioned project was developed as a graduate qualification work at the Academy of Watercolor and Fine Arts of Sergey Andriaka under the supervision of the Honored Artist of the Russian Federation and Associate Member of the Russian Academy of Arts A. B. Popov. The authors of the article discuss the problem of selecting appropriate composition formats and their subsequent mirroring in relation to the centerpiece of the series at its preliminary sketching stage. The article touches upon the question of proper space composition in symmetrical images, i.e. how to convey a similar depth of couple pieces in the series. The fundamental techniques for working with the tonal color scheme are unveiled, namely the simultaneous portrayal of unity and contrast of lights and shadows in the pieces symmetrical to the central one. Furthermore, the paper addresses how to wisely choose a technique optimal for the type of etchings belonging to the series. The concurrent usage of aquatint and etching stroke technique is justified as it allows one to combine detailed object drawing with decorative aquatint painting as a compositionally organizing element. Likewise, the authors delineate the principles for selecting appropriate printing ink, particularly in the light of the use of a painterly “two-color printing effect” (application of a warm-cold effect of one ink in layers of different thickness). The article will be useful for teachers and students of art schools at all levels of education, photographers and designers, as well as anyone who is interested in creating a series of visual art works.
