Directions for Ingento Blue Print Powder
Paper instruction sheet is folded into quarters, and was stored rolled around the tube to fit into the rectangular box. When unfolded the corners curl from being rolled around the tube, and deep creases are evident. The paper is an off-white color with navy blue text. An example photo appears near the upper left corner of the insert to demonstrate the effects of using blue print developing powder.
INGENTO/ BLUE PRINT/ POWDER/ TUBE// There are no more/ attractive or artistic prints than Blue Prints/ when the blues are bright/ and the whites are clear, nor/ is there any printing process/ so simple to manipulate or so/ inexpensive. Blue Prints can/ be made on almost any ma-/ terial, such as note paper, en-/ velopes, cards, silk, linen, can- /vas, etc., with little time and / ordinary care.// The best results are obtain-/ed when the material is used/ freshly coated, and the chemicals are pure.//[bolded] The Directions [bolded] for preparing the material are very simple, and may be given/ briefly as follows:--Dissolve the contents of one tube in 1 oz of water, coat, dry, / and print in the ordinary way; but to prevent failure we give all of the necessary/ precautions as follows:// Use pure water if possible; distilled, rain, or well boiled water. Filter the/ Solution through a linen cloth and coat the paper or cloth in a dim light with a / clean sponge, tuft of cotton or brush, and then hang up to dry in a dark place./ Make the prints while the material is freshly coated. Print in ordinary print-/ ing frames. Prints should be made rather deep so as to allow of ample washing/ afterwards. When the printing is done all that is necessary is to give them a/ thorough washing in running water. They may be dried between blotters, or/ mounted wet. When a small portion of cloth is to be sensitized it is better to use/ embroidery hoops. The Solution should be kept in a small bottle inside of a small/ dark box, as it will deteriorate if exposed to a strong light. // TONING BLUE PRINTS// Blue Prints may be toned to sepia, chocolate, or even black, at any time, by/ the following method:--Immerse the print in a saturated solution of Sodium Car-/bonate until the image has disappeared; wash in several changes of water, and/ then transfer to a saturated solution of Tannic Acid. The longer it is left in this / solution the deeper the tone will be. After toning, they are washed in the usual/ manner; dried and mounted--no fixing required.//Price, Per Tube---10 cents// BURKE & JAMES//CHICAGO//
