Andy Warhol’s Blotted Line

Learn Andy Warhol's blotted line process by combining drawing with basic printmaking skills.

Overview

This lesson features Warhol’s early drawing technique that incorporates a basic printing process. Students use critical thinking skills to judge commercial advertisements and to make decisions on what they will include, embellish, and edit out of their own drawings.

Grade Level

  • Elementary School
  • Middle School
  • High School

Subject

  • Arts
  • English and language arts

Objectives

  • Students examine visual and written data.
  • Students identify, describe, and analyze Warhol’s use of design elements.
  • Students use materials to learn the drawing/printing process and how to apply watercolor and gold leaf.
  • Students make aesthetic decisions (color, line, etc.) in their work to create a particular visual impact.
  • Students predict marketability to an intended audience.
  • Students establish criteria for successful advertising.

About the Art

Warhol’s drawing The French Look is one of many shoe illustrations he created using a type of line drawing known as the blotted line technique. Warhol first experimented with blotted line while still a college student at Carnegie Institute of Technology (now Carnegie Mellon University). He continued to craft this technique in his commercial work in New York City throughout the 1950s. Blotted line enabled Warhol to create a variety of illustrations along a similar theme. This type of production allowed him to bring multiple ideas to clients to increase the odds that one of his drawings would be chosen for the final advertisement.

Blotted line combines drawing with basic printmaking. Warhol began by copying a line drawing in pencil on a piece of non-absorbent paper, such as tracing paper. Next, he hinged this piece of paper to a second sheet of more absorbent paper by taping their edges together on one side. With a fountain pen, Warhol inked over a small section of the drawn lines. He then transferred the ink onto the second sheet by folding along the hinge and lightly pressing or “blotting” the two papers together. The process resulted in the dotted, broken, and delicate lines that are characteristic of Warhol’s illustrations. Warhol often colored his blotted line drawings with watercolor dyes or applied gold leaf.

I was getting paid for it, and I did anything they told me to do. If they told me to draw a shoe, I’d do it, and if they told me to correct it, I would—I’d do anything they told me to do, correct it and do it right.

Points of View

Another reason why he liked it [the blotted line technique] so much [was that] by having your master drawing with which you made your blot, you could keep blotting it and redrawing it and blotting it each time and make duplicate images.

It was absolutely true that he could draw anything and very, very quickly. And, so, we used him a lot.

Andy and I began a campaign, which was unprecedented at the time. We ran full pages, half pages, every Sunday in the New York Times. And it was a spectacular showcase for I. Miller and for Andy as well. It expanded his audience in a way that no magazine editorial ever could have. In a sea of tiny little images that were the pages of the Times, these bold blockbuster fantasies were extraordinarily effective. What the ads did was to revitalize and revive the I. Miller brand, and from a dowdy, musty, fusty, dusty, dowager establishment, it became a stylish emporium for debutantes.

Discussion Questions

  1. Use adjectives to describe the lines and colors Warhol used in his drawings.
  2. Did Warhol draw in all the details? What is left out? Why?
  3. What type of person do you think Warhol was trying to attract with these ads? Explain your answer.
  4. When you look at advertisements, how do artists and designers manipulate images to make products seem more appealing? (Look through magazines to find examples.)
A magazine advertisement for a pair of Leon Max shoes. The shoe, a brown leather, high-heeled ankle boot, is pictured sitting on a branch, surrounded by leaves.

A piece of tracing paper has been placed over a Leon Max magazine advertisement. A pair of hands use a pencil to trace the outline of a shoe featured in the ad.

With the tracing paper attached to a piece of watercolor paper, a student uses a paintbrush to apply ink to the image of a shoe that they have drawn on the tracing paper.

Student begins to apply ink over the shoe outline

After applying ink to the image of a shoe on a piece of tracing paper, a pair of hands presses the tracing paper to the piece of watercolor paper to which it has been attached, transferring the image.

Student blots ink onto watercolor paper

The student pulls away the piece of tracing paper, revealing that the image of a shoe has been transferred to the watercolor paper.

Student continues to ink and blot the tracing until entire image has been transferred onto the watercolor paper

Materials

  • Pencils and dark markers
  • Ink pens and nibs
  • India ink
  • Dr. Martin’s watercolor dyes
  • Source images
  • Paper towels
  • Tracing paper
  • Arches 88 or Coventry Rag paper
  • Clear tape
  • Gold leaf
  • Aquasize and Aquasize brushes
  • Watercolor brushes
  • Paint trays and containers

Procedure

  1. View The Warhol’s blotted line technique video on YouTube.
  2. Cut full sheets of Arches 88 or Coventry Rag paper into smaller sheets. Cut tracing paper to corresponding sizes.
  3. Collect a range of magazine source images (e.g. models, shoes, perfume, jewelry, etc.).
  4. Select a source image, then tape a piece of tracing paper on top of the image. Trace the lines of the source image onto the tracing paper with a pencil. Trace over the penciled line with black marker. Next, hinge the tracing paper with tape to the Arches 88 or Coventry Rag paper.
  5. Opening the papers like a book, ink a small part of the traced drawing, then lightly blot the ink onto the watercolor paper with fingers or the opposite end of the ink pen. Continue to ink and blot small segments at a time until the drawing is finished. Dr. Martin’s dyes or gold leaf can be used after the ink is dry to fill in the drawings.
  6. When using gold leaf, apply a thin layer of Aquasize on selected areas and wait for it to become tacky before placing pieces of gold leaf on top.

Wrap-up

Have students hang their drawings next to their original source material. On a separate piece of paper, ask students to identify what they chose to include and embellish and what they chose to exclude for the original source in their final illustrations. Using a rating scale from 1–5 (five being the highest rating), have students assess the appeal of their product illustrations. Students should write a sentence or two explaining their rating. As a class, discuss which drawings are successful, which are not, and why.

Extension

If there is time, make a series of drawings from the same source image with alterations to color, decoration, and impact.
