Most diplomas and a lot of legal documents are authenticated by the application of a raised seal. The procedure is called embossing and the machine employed is an embosser. Embossers are likewise used to create a raised return address on requests to participate or be present and personalize books. The embossing may be done directly on the paper if not thick or on a self-adhesive foil wafer. The wafer is pealed off the paper liner and placed on the paper.

The routine is easy to understand. An electronic effigy file is sent to a laser that engraves a positive and negative die. On the positive die the white or un-embossed part of the effigy is burned away leaving the black percentage of the effigy raised. Then the negative die is lasered and the black or raised portion is burned away leaving the effigy as a depression in the die. The black effigy is somewhat wider strokes so there is room for the paper. The two dies are lined up and attached to a die holder, which slips in and out of the embosser body. You may get assorted dies on die holders and switch to change the image. Thus one embosser may emboss dissimilar images by swapping the dies. The dies are interchangeable among in embossers that are the same manufacturer and throat. The throat is the greatest or most complete or best possible distance from the center of the effigy to the edge of the paper. Seals come in handheld, desk, long reach (2.5 inch), and extended long reach (4.5 inch). Avoid very cheap embossers as a heap of do not have the dies parallel in the embosser and the effigy is heavy on one side and disappears on the other.

The hand of the embosser is the direction the paper is inserted. If the embosser comes up from the bottom then the hand is bottom. Bottom is the default. You must specify the hand at the time of order and it is not adjustable. If you emboss from the right side with a bottom handed embosser the effigy will be sideways. If you emboss from the top of the page with a bottom handed embosser the effigy will be upside down. Foil wafers make the hand not relevant since they are pealed off the carrier and attached to the document.

Embossers are designed to emboss light text weight papers. A 20-pound text is usable but 28 pound and above may cause problems. The thicker the paper the harder it is to emboss. The negative die needs to be cut deeper and wider to concede for thicker paper and there are severe limits on paper thickness. Paper does not stretch and embossing many times causes micro fractures in the embossed image. Foil wafers on the other hand are more elastic so it does not micro fracture like paper.

When embossing directly on paper the effigy may not show up well on photocopies of the document. There is a 2-inch round solid inkpad that may help here. You hold it by the flip up handle and gently touch the inked surface to the raised embossing causing the raised [portion to turn black.

One mystery of getting a good effigy is in preparing the artwork. The electronic art file must be either a vector graphic or a 600 dpi tiff file at the finished size (a 2′ inch seal @ 600 dpi is 1200 x 1200 pixels) The effigy must be black and whit only (no colors or grays) The most mutual errors in preparing your effigy file are Mistaking a dark gray for black, too low a resolution, not using an actual vector art file, and failing to outline the fonts. If you use Photoshop, you ought to save it as a 600 dpi tiff file. Photoshop’s .eps is not a true vector graphic and does not work properly. If you use illustrator or another real vector art program and save it as an esp. be sure to outline the fonts used first. This makes the font a portion of the graphic and not a font referenced on your computer (which may not be on the computer at the factory where the embosser is prepared). I have run into images that were submitted in RGB, CYMK, or grayscale, which looked like black and white but did not work. Select bitmap mode in Photoshop and see what happens to the image. If the black breaks up into a salt and pepper pattern then you are dealing with a shade of gray. Replace the gray with a unfeigned black.

The effigy file will have to integrate bold fonts without fine lines and images with out fine detail. Embossers can not hold fine detail in the image. Typically an embosser would have text in a circle amidst an outer and inner circle and a graphic in the center. The pricing of an embosser is based on the reach, die size, and whether client supplied graphics are used. Many embosser manufacturers have stock graphics that may be use as the center without further and added cost and they price those embossers as they would a text only. For example you could have your name in an arc among the inner and out circle on the top and Notary Public on the bottom with the official seal of your state in the middle and it still counts as a text only embosser for pricing. Text may be in an arc at the top and a discerned arc at the bottom bout being right side up or in one continuous arc. If the inner and outer circles are solid circles they will have to be broader to prevent the embosser from cutting through the paper. An substitute procedure is a broken line that resembles rope.

Embossers are available in 1×2 rectangular, 1 5/8, 1/3/4, and 2 inch die sizes. The more prominent the die the better is embossing paper directly. Another contemplation will have to be considered if foil wafers are used. Most wafer manufacturer measure the size from point tip to point tip through the diameter. If you have a 2-inch seal and a 2-inch effigy die then the effigy will go out to the tip of the points on each side. A 1 3/4 or 1 /5/8 inch embosser fits better on a 2 inch embosser die 2 inch seal are available in a wide assortment including metallic gold, metallic silver, metallic bronze, metallic red, metallic green, and metallic blue. If you need a 2 1/4 or 2 1/2 inch seal you choice are far less and they are harder to find and more expensive.

An substitute to using an embosser is to buy pre-embossed seals. These seals are embossed in a factory so all are utterly centered and even. You peal them off a roll and apply them to the paper. Besides being perfective and ready to use, they may have background ink in the lowlands making them look far more professional than what you get from your embosser. You may get them in gold, silver or bronze foil in 170 sizes and shapes. You may have them embossed only, embossed with a similar tinted background ink, or with a contracting ink (like dark blue ink on a gold foil) There are 16 stock ink colors available at no further and added cost. With a surcharge you may get Pantone ink colors. It is possible to get up to 4 dissimilar background inks as long as the inks have a 2 pixel wide embossed area as a dike to keep the ink separate.
