 General Instructions 
 
 THE paper is exposed to daylight in contact 
 with the negative in the printing frame, in 
 the usual manner. 
 The exposed print is then immersed in the 
 developer for from i to 4 minutes till fully developed, 
 then cleared in four acid baths containing i ounce 
 of Muriatic Acid C. P. to 60 ounces of water [half 
 these proportions for Sepia prints) and washed for 
 a short time in running water. The whole oper- 
 ation of printing, clearing and washing being com- 
 plete in about one hour. 
 
 N. B — The Developing Salts are the special salts recommended 
 by Willis & Clements for development, and are sold in 3^ lb., J^ lb. 
 and 1 lb. boxes. 
 
 The salts are mixed in definite proportions and 
 must all be dissolved at one time, otherwise the 
 tone of the prints will not be uniform.

 Permanent Prints. 
 
 Treatment of ttie Paper 
 
 To secure the most brilliant results the sensitized 
 paper, be/ore, during- and after its exposure to light, 
 must be kept as dry as possible. 
 
 It is necessary to place between the sensitized 
 paper and the pads a sheet of thin India-rubber 
 cloth; it is of the first importance that the pads 
 in contact with the paper be quite dry. 
 
 The effect of damp is seen in a want of vigor, a 
 general muddiness of tone, and, where the sensi- 
 tized paper has been exposed to its influence for 
 some days, in the impaired purity of the whites. 
 
 Platinotype papers keep for many months if 
 stored in a cool, dry place in the tins in which the 
 paper is supplied. 
 
 N. B. — It is very important that the lid of the tin be properly 
 sealed with rubber band or rubber tape to keep out the air. 
 
 During the winter, or in high altitudes where the 
 air is dry, the paper will keep for many months 
 without the slightest deterioration, though it should 
 not be stored in a hot room. 
 
 In most places American summers are both hot 
 and damp, especially along the coast and in the 
 cities near the great lakes, and in southern latitudes 
 during the wet season. The constant evaporation 
 saturates the air with moisture, causing the hot- 
 damp conditions so destructive to photographic 
 papers ; but, even in such climates, Platinotype 
 
WILLIS & CLEMENTS, PHILADELPHIA. 
 
 papers may be kept safely without danger of spoil- 
 ing. It is, however, essential that the tube in which 
 the paper is packed be stored in a cold or cool 
 place. 
 
 N. B. — If only part of the dozen pieces of paper be taken out of 
 the tube for use at one printing, the balance, with the lump of pre- 
 servative, should be returned to the tube and a rubber band secured 
 around the lid. Diuring the summer it is advisable to use the whole 
 contents of the tube the same day it is opened. 
 
 Exposure to Light 
 
 The correct exposure is ascertained by inspection 
 of the paper in a rather weak white light in the 
 usual manner. A little experience will enable the 
 exposure to be determined very accurately. 
 
 Platinotype can be printed by the Cooper Hewitt 
 Light (see our circular regarding this method). 
 
 As a general rule all parts of the picture except 
 the highest lights should be visible when the 
 exposure is complete. 
 
 When examining the prints in the printing frames, 
 care should be taken not to expose them unduly to 
 light. The tinting of the whites of the paper due to 
 slight action of light is not visible until after development. 
 
 Damp paper gives a less visible image in the printing 
 frame than dr>' paper, hence it may easily be over- 
 exposed. 
 
 When printing from thin negatives care must be 
 taken not to over-expose. As soon as the image is 
 faintly visible it may be considered enough. 
 
 Thin, flat negatives give weak prints, whether 
 sepia or black. 
 
WILLIS & CLEMENTS, PHILADELPHIA. 
 
 Development of Black Prints 
 
 The whole contents of the box of developing 
 salts must be dissolved at one time. If this be not 
 done, too large a proportion of one of the ingredi- 
 ents may possibly be used. 
 
 Development should be conducted in a feeble 
 white light, similar to that used when cutting up the 
 paper, or by gas light. 
 
 It may take place immediately after the print is 
 exposed, or at the end of the day's printing. 
 
 Develop by floating the print, exposed side down- 
 wards, on the developing solution, or, it may be 
 immersed. 
 
 ^^The Extra Heavy Papers require much long- 
 er developing than the thinner papers. They may 
 be given as long as from three to four minutes in 
 the developing bath without injury. All our papers 
 produce better prints from a/i<// development. 
 
 It is also important that the heavy papers be well 
 cleared in the acid baths. They should have never 
 less than four baths. 
 
 During the hot summer days it is not advisable to 
 delay the development of exposed prints. If 
 possible develop within one hour after printing. 
 
 Either porcelain or agate — preferably porcelain — 
 dishes are necessary to hold the developing 
 solution. 
 
 Use good-sized dishes and plenty of solution. 
 
WILLIS & CLEMENTS, PHILADELPHIA. 
 
 Remarks Upon Development 
 
 Always rock the developing bath, or stir the 
 solution between each development ; this will break 
 up any scum which may be left by the previous 
 print. 
 
 The Developer for "cold bath" may be warmed. 
 At a temperature of about 120° Fah. under-exposed 
 prints may often be saved. It is usual for a warm 
 Developer to give rather warmer tones. It is not 
 advisable to use a bath at a lower temperature than 70° 
 nor above 120° Fah. If a lower temperature be used 
 it tends to give coarse, granular prints ; if too warm 
 a bath be used it is liable to give brown-black tones 
 in place of pure black. 
 
 The bottom of the developing dish should be 
 covered with the developing-solution to the depth 
 of at least one-half of an inch. 
 
 After the prints have been developed pour the 
 solution, without filtering, into a bottle for future 
 use; it should not be exposed to a strong light. 
 When next developing, the solution will be found 
 to be nearly clear, but, of course, tinted by previous use. 
 If this clear solution be not sufficient for use, add 
 to it some of the fresh "stock" developing solution. 
 It is a safe plan always to keep the " bath solution " up 
 to its original bulk by this means. Any suspended 
 matter in the bath should be filtered out. 
 
 Sometimes, when a large number oi prints (or large 
 prints upon small bulk of solution) are developed at 
 one operation, the bath will become so loaded with 
 
WILLIS & CLEMENTS, PHILADELPHIA. 
 
 chemicals derived from the paper that it will no 
 longer give good prints. Such a solution must at 
 once be replaced by a new one. When working 
 on a somewhat large scale it is especially necessary 
 to watch for any change in the quality of the prints; 
 and in case of a doubt a new bath should be tried. 
 
 Should prints be grey and granular, one of the 
 following suggestions will be found to be the cause: 
 
 1. Insufficient development of the exposed print. 
 
 2. Granular and weak negative. 
 
 3. Developer too weak, or, possibly, too cold. 
 
 Clearing and Washing 
 
 To clear the developed prints: these must be 
 washed in a series of baths (not less than four) of 
 a weak solution of Muriatic Acid C. P. This solu- 
 tion is made by mixing one part Muriatic Acid with 
 60 parts of water. The acid should be colorless. 
 On no account should commercial Muriatic Acid 
 be used. Citric Acid, in the proportion of i ounce 
 to 20 ounces of water, may be used. This softens 
 the paper in less degree than does the Muriatic 
 Acid. 
 
 As soon as the print has been removed from the 
 developing-dish it must be immersed face downwards 
 in the first bath of this acid, contained in a porce- 
 lain dish, in which it should remain about five min- 
 utes ; meanwhile, other prints follow until all are 
 developed. The prints must then be removed to a 
 second acid-bath for about ten minutes j afterwards 
 
WILLIS & CLEMENTS, PHILADELPHIA. 
 
 to the third bath for about fifteen minutes, and a 
 fourth bath for five minutes. While the prints re- 
 main in these acid-baths they should be moved so 
 that the solution has free access to their surfaces. 
 
 Don't handle the prints roughly or they will be- 
 come dented and the surfaces rubbed. 
 
 Pure Muriatic Acid must be used. 
 
 If Commercial Muriatic Acid be used, the prints 
 will turn yellow. 
 
 For each batch of prints fresh acid-baths must be 
 used. 
 
 After the prints have passed through the acid- 
 baths, they should be well washed in four changes 
 of water during about a half hour. It is advisable 
 to add a pinch of washing soda to the second wash- 
 ing water to neutralize any acid remaining in the 
 print. Do not use water that contains iron, as it 
 tends to turn paper yellow. Soft water is the best 
 for this purpose. 
 
 Drying Platinotype Prints 
 
 In establishments where a large number of prints 
 are turned out daily, a good method is to hang 
 the wet prints back to back on wires stretched 
 across the room, using clips to grasp the edges of 
 the two prints. 
 
 Possibly a better way is to lay the wet prints 
 between dr}' blotters, changing them two or three 
 times and placing a weight over a glass plate or 
 flat board on top of the pile.

 Instructions tor the Use of tlie 
 Sepia Papers— Not Japine 
 
 With a few exceptions the method of carrying 
 out the operations is the same as for the " black" 
 kinds of Platinotype Paper. The following points 
 should be attended to : — 
 
 The "Sepia" paper is more easily affected by 
 faint light, and, therefore, increased care must be 
 taken when printing. 
 
 To develop, dissolve the Sepia Crystals precisely 
 in accordance with directions on the label, and heat 
 to a temperature of 150° to 190° Fah,, to obtain the 
 greatest amount of brilliance and the warmest 
 color. Very good results can be obtained by 
 using a cooler developer. 
 
 The development of the exposed print is effected 
 by immersing it in the developer heated as above, 
 or it may be floated on the surface of the devel- 
 oper. 
 
 The solution is conveniently contained in a fiat- 
 bottomed dish, heated by a gas or oil stove. 
 
 Greater care must be used with Sepia than with 
 black paper, to avoid exposure to light, both when 
 examining the prints and even in the first acid-bath, 
 otherwise the whites will be discolored. 
 
WILLIS & CLEMENTS, PHILADELPHIA. 
 
 Discoloration of the whites is due to one of the 
 following causes : — i. Too much exposure of the 
 developing solution to light ; 2. Use of a dish in 
 which the enamel is cracked so as to expose the 
 iron ; 3. Paper kept too long ; 4. Exposure of 
 prints to too much light before or after printing. 
 
 The prints are cleared in four acid-baths of i 
 part Muriatic Acid C. P. to 120 parts of water. 
 
 As the "Sepia" prints, unlike the "black" ones, 
 may be afifected by light when in the acid-bath, the 
 lights being stained and degraded, the prints at this 
 stage must be manipulated in a weak light — gaslight 
 will be quite safe. The prints are damaged by be- 
 ing left too long in the acid-baths. 
 
 The subsequent operations are the same as for 
 the other kinds of paper. 
 
 Agate dishes, carefully heated, are the most use- 
 ful for the Sepia developer. 
 
 An agate dish which has been used once in devel- 
 oping Sepia prints, should not be afterwards used 
 in developing black toned prints. 
 
 The Sepia Papers are now made in KK, TT, 
 YY, Japine K, Y and BuiT.

 Japine Sepia 
 
 This !• a matt Sepia paper of beautiful quality, giving exquisite 
 
 prints possessing a rich sepia tone. The prints are 
 
 PURE PLATINUM and Permanent 
 
 DIRECTIONS 
 
 Printing. The same as for our other Platino- 
 type papers. 
 
 Developing. Dissolve the salts precisely in 
 accordance with the directions on the label and 
 heat to a temperature of 150° to 170° Fah. The 
 exposed prints should be immersed in the solu- 
 tion : full development will be effected in about 
 fifteen seconds to half a minute. 
 
 Used developers should be strengthened every 
 day with fresh solution and any particles of sedi- 
 ment filtered out. Do not overheat the developer. 
 Use a thermometer. 
 
 Clearing the Prints. Pure Muriatic 
 Acid — I oz. ; water — 60 ozs. Four baths are neces- 
 sary: the first, five minutes; the second, ten min- 
 utes; and the last two, fifteen minutes each. It takes 
 a little longer to remove the iron from Japine papers. 
 Wash the prints inrunningwater, orseveral changes 
 of fresh water, during about twenty minutes. 
 
 Drying Japine Prints. Japine prints must 
 be dried between clean, dry blotters — changing 
 from two to three times. Blotters may be easily 
 dried by suspending them by clips.

 IVORY BLACK 
 
 IS A PURE 
 
 Platinotype Paper 
 
 and worked precisely as our other 
 brands, but it will be noticed that 
 Ivory Black paper prints more 
 rapidly and requires a warm devel- 
 oper. 
 
 Directions 
 
 Print with slightly less visibility of the 
 exposed image and develop at a maximum 
 temperature of 140 deg. A cooler bath may 
 be used, but the prints will be colder in tone. 
 The developing solution once used for this 
 purpose must be kept especially for IVORY 
 BLACK papers. Negatives of the strength 
 suitable for our other papers will be found just 
 right for IVORY BLACK.
