question: How do images get printed on cakes or beer foam?
comment: Same with home inkjet printer. Just that the ink that's used is edible ink. Tiny nozzles spray high pressurized ink onto a print media, in this case a cake or coffee foam
passages: Edible ink printing is also used in decorating cakes. After breakthroughs in nontoxic inks and printing materials in the early 1990s, it became possible to print images and photographs onto edible sheets for use on cakes. It is the process of creating preprinted images with edible food colors onto various confectionery products such as cookies, cakes, or pastries. Designs made with edible ink can be created with an edible printer, a specialty device which transfers an image onto a thin, edible paper. Edible paper is made of starches and sugars and printed on with edible food colors. Originally introduced as a specialty service provided by bakeries, this technology can now be used by home consumers using the specialized paper, ink and printers.
   U.S. Patent 6,319,530 describes a "Method of photocopying an image onto an edible web for decorating iced baked goods". In other words, this invention enables one to inkjet print a food-grade color photograph on a birthday cake's surface. Many bakeries now carry these types of decorations, which are printable using edible inks and dedicated inkjet printers. Edible ink printing can be done using normal home use inkjet printers like Canon Bubble Jet printers with edible ink cartridges installed, and using rice paper or frosting sheets.
   Each graphic artist has their own set of skills in creating their work, but there are several basic starting points for edible dessert art. Most edible art franchises have sheet cakes, cut-out sheet cakes, layered cakes, sculpted cakes, and tiered cakes to choose from as a foundation. One common technique is to airbrush the piece with sugar to enhance its features. Many artists in this field have a degree in fine arts, and participate in freelance decorating.

   Edible ink printing
  
  Edible ink printing is the process of creating preprinted images with edible food colors onto various confectionery products such as cookies, cakes and pastries. Designs made with edible ink can be either preprinted or created with an edible ink printer, a specialty device which transfers an image onto a thin, edible paper. Edible paper is made of starches and sugars and printed with edible food colors. Some edible inks and paper materials have been approved by the Food and Drug Administration and carry its generally recognized as safe certification.
   In 2012, automatic machines for making sugar paintings started to appear in the market. Once sugar is added, the machine is programmed to paint on a plane in a process similar to automatic engraving. It does not need any art skills or experience, and is easy to operate. There are hundreds of graphics than can be painted using this machine.

   In blown sugar, a portion of pulled sugar is placed on a rubber pump which is tipped with either wood or metal. Pumps are most commonly hand pumps. While being blown, the sugar can be shaped, often into animals or flowers. Blown sugar cannot be quickly cooled by dipping it in water, so chefs must use fans to cool the sugar, all the while rotating it, so that it does not come out of shape. This technique is very useful in making balloons for wedding cakes.

   Cake Wrecks
  
  Cake Wrecks is an entertainment website featuring user-submitted photographs of professionally made cakes that are unintentionally humorous or strange in appearance. Founded in May 2008, inspiration for the confectionery-themed photoblog began when site-master Jen Yates received an e-mail that included a photo of a sheet cake, decorated with a customer's verbatim request: "".
  
  Section::::History.
   Cake design is an imagining of a cake as copyrightable art, like a sculpture.
  
  Bakeries which provide cakes which critics have ridiculed for low quality have sometimes sought to claim copyright over their cakes. The copyright claim is part of an attempt to enforce demands that communities of people who mock cakes not publish photos of cakes for entertainment.

   Etched patterns range from simple geometric shapes to complicated drawings, such as crosshatching, images of animals and flowers, and are generally performed with a coffee stirrer of some sort. Etched latte art typically has a shorter lifespan than free poured latte art as the foam dissolves into the latte more quickly.
   The liquid sugar is blended with a small amount of royal icing. The heat from the sugar causes the air incorporated in the icing to rapidly expand, causing the mixture to grow to several times its original volume. The mixture is quickly poured into a lined dish, and placed into a blast chiller to set. This process produces a sugar mass with the texture of volcanic pumice, the color of which is determined by the color of the sugar syrup.

   The sugar has been cooked, and the now-liquid sugar is poured onto a silicone rubber mat. Any coloring is now added. The sugar is then folded repeatedly into itself, until the sugar is, while still flexible, cool enough to handle. The sugar is then stretched out and then folded on itself repeatedly. This process incorporates air into the sugar, and gives it a bright lustery sheen. The sugar can then be sculpted by hand into various shapes, made into ribbons, or blown.

   "Cake" opens on a baker cracking eggs into a mixing bowl to the opening strains of "My Favorite Things", performed by Julie Andrews. This begins a montage of shots of white-uniformed cooks moving trolleys of ingredients and performing cake preparation work such as zesting oranges and mechanically mixing cake batter. Several large blocks of madeira cake are taken from the oven, starting a time-lapse sequence of the brick-like cakes being arranged into a pile and being mortared with buttercream icing. After a shot of gloved hands kneading orange sugar paste, a woman pours melted chocolate into a pot of Rice Krispies. The sugar paste is pressed between rollers, and the pot of Rice Krispies emptied into a mould. Layers of Battenberg cake are mortared together with raspberry jam. The Rice Krispies are removed from the moulds and arranged as panels around the madeira structure, creating the rough outline of a car. Jelly mixture is poured into a mould while another cook attaches Fox's Glacier Mints to a fondant base to create a headlamp. Long lines of liquorice are wrapped as belts around pieces of a madeira engine. A tin of golden syrup is poured in place of lubricant. The engine is lowered into the front of the car while pastry chairs are lowered into the interior. The jelly mould is removed to reveal a brake light, and a tyre made of chocolate fondant is wheeled in and various details such as liquorice windscreen wipers and a front grille made of chocolate Flakes are added to the car. The bonnet is lowered and icing sugar is dusted onto the roof before a fondant Škoda logo is attached to the front. The closing shot is of the team lined up around their creation, which now appears to be a cake replica of a Škoda Fabia, with the tagline "The new Fabia. Full of lovely stuff." across the bottom.
   Post-production work was performed by Tom Sparks of Alteration Services, with video editing conducted by The Quarry. Ancillary elements of the campaign, such as the online presence and direct marketing, were handled by advertising agency Archibald Ingall Stretton, who had worked with Škoda for eight years prior to "Cake". The online elements of the campaign included a dedicated microsite, which was linked to through baking-themed banner ads placed on the sites such as "The Times Online", AOL, and "Top Gear". For the direct marketing portion of the campaign, Archibald Ingall Stretton sent out car-shaped a double-chocolate, toffee-fudge cream scented air fresheners in the mail to potential and former clients.
   Although techniques vary, normally the hot sugar is drizzled from a small ladle onto a flat surface, usually white marble or metal. The outline is produced with a relatively thick stream of sugar. Then, supporting strands of thinner sugar are placed to attach to the outline, and fill in the body of the figure. These supporting strands may be produced with swirls, zig-zags, or other patterns. Finally, when completed, a thin wooden stick, used to hold the figure, is attached in two or more places with more sugar. Then, while still warm and pliable, the figure is removed from the surface using a spatula-like tool, and is sold to the waiting customer, or placed on display.
   The cakes are produced from a batter which includes flour, sugar, cocoa and water. It is baked in trays for 17 minutes in a conveyor oven that can turn out 11,000 cupcakes an hour. After cooling, the cakes are injected through the top with the vanilla creme, then taken by conveyor to be covered on top by chocolate icing. After a special machine lays white icing in the signature squiggle the cakes are cooled then wrapped.
   A finished cake is often enhanced by covering it with icing, or frosting, and toppings such as sprinkles, which are also known as "jimmies" in certain parts of the United States and "hundreds and thousands" in the United Kingdom. Frosting is usually made from powdered (icing) sugar, sometimes a fat of some sort, milk or cream, and often flavorings such as vanilla extract or cocoa powder. Some decorators use a rolled fondant icing. Commercial bakeries tend to use lard for the fat, and often whip the lard to introduce air bubbles. This makes the icing light and spreadable. Home bakers either use lard, butter, margarine, or some combination thereof. Sprinkles are small firm pieces of sugar and oils that are colored with food coloring. In the late 20th century, new cake decorating products became available to the public. These include several specialized sprinkles and even methods to print pictures and transfer the image onto a cake.
   Mässmogge are produced largely by hand in a complicated process. The candy mass, made of sugar, glucose and water, is warmed to 134 degrees Celsius, agitated in order to become airy and white, colored and folded into a striped, layered paste. The filling, consisting of roasted and ground hazelnuts with some fat and sugar, is then spread over the candy mass. The paste is wrapped into a roll, which is drawn out by a machine to a length of about , and separated into the individual Mässmogge. The whole process must take no more than 25 minutes, in order to keep the candy mass warm and malleable.
   Latte art requires first producing espresso with crema and microfoam, and then combining these to make latte art. See microfoam: procedure for how microfoam is made; this article concentrates on the latte art once the foam is made.

   Using a small charcoal stove, sugar is heated in a metal vessel. When at the correct temperature, a ball is extracted. It is then kneaded in the artist's hands to product consistency and pliability. A thin straw is then inserted into the ball, and the artist begins to blow air into it, in order to slowly inflate it. Simultaneously, the artist pinches and pulls parts of the ball, by hand, or sometimes with tools such as tweezers, to produce limbs, and various shapes. Before the figure has completely cooled, colours, typically red or green, are added to the surface, and a wooden stick is inserted into the underside. The straw is then extracted, and the figure put on display for sale.
