What is cel animation—and how do anime cels work?

Cel animation is a traditional, hand-drawn animation method that paints characters on transparent sheets (cels) and layers them over backgrounds. ArtCel is the cel-materials brand of LOPPO, LLC. (有限会社六方), supplying modern sheets, paints, and pegs for artists and learners.

ArtCel cel animation materials by Loppo

What is cel animation?

Cel animation is a form of traditional animation: drawings are transferred onto clear plastic sheets, colored (often from the reverse side), stacked as needed, and photographed over a background. It is one route within hand drawn animation—motion is planned on paper, while the cel carries the finished painted layer used for shooting or display.

What is an anime cel?

An anime cel usually means a painted transparent sheet from an anime production pipeline (or a similar finished painted cel). Blank animation cels are different: unused clear sheets sold so you can paint new work. Loppo’s ArtCel line is about blank sheets, paints, and tools for making new cels—not trading or appraising vintage production art.

Traditional and hand-drawn animation in practice

In traditional animation studios, hand drawn animation often combined key drawings, in-betweening, ink-and-paint on cels, and camera work. Digital ink-and-paint largely replaced physical cels in commercial TV production, but the logic of layers, registration, and reverse-side color still matters for teaching, workshops, and analog experiments.

What ArtCel and Loppo provide

ArtCel supplies clear sheets, opaque flexible paints, and alignment tools chosen for today’s cel painting—not claims of matching every historic studio formula. LOPPO, LLC. operates from Shibuya, Tokyo, and offers workshop routes plus production-education consultation for teams that want to use cel technique intentionally.

Frequently asked questions

What is cel animation?

Cel animation is traditional hand-drawn animation that uses transparent sheets (cels) for painted character layers over backgrounds. After digital production became standard, physical cels became rare in commercial pipelines, but the technique remains useful for art, education, and experimental work.

What is the difference between an anime cel and blank animation cels?

“Anime cel” often refers to a painted production sheet from an anime title or a similar finished piece. Blank animation cels are unused transparent sheets sold so you can paint new work. ArtCel focuses on blank sheets and paints for making new cels, not on selling vintage production art.

Is cel painting the same as all hand-drawn animation?

No. Hand-drawn animation includes many paper-only or digital workflows. Cel painting is one traditional route that separates line and color on a transparent support. It is related to traditional animation history, not a synonym for every hand-drawn style.

Can beginners try cel painting?

Yes. The basic workflow is straightforward: trace the line art, paint from the reverse side, let it dry, and place it over a background. Loppo also offers workshop routes in Tokyo for people who want hands-on support.

Are ArtCel materials the same as old studio materials?

ArtCel materials are modern practical materials selected for cel painting today. They support the properties needed for reverse-side painting without claiming to be identical to every discontinued historic supply.
