The tenth edition of the “BCBF Visual Identity Workshop” celebrates ten years of visual design and creative exploration.
Korean artist Bumi Cha is the author of the new image for the Bologna Children’s Book Fair 2026.
The Chialab team takes us behind the scenes of the workshop, sharing the process that led to the creation of this year’s visual identity..
10 years of the Visual Identity Workshop (VIW)
Bologna 19 July 2025 7:55am
Dear Elena,
VIW BCBF 26 came to an end yesterday amid some small gifts, ice cream and teary eyes. Bumi was highly attentive, delicate, tireless and insatiable for suggestions. Her big dark eyes took everything in, while expressing a mix of curiosity and trepidation. Words, on the other hand, were more of an obstacle, as digital translators were not so effective at translating between Korean, English and Italian. Fortunately, practical exercises, constant drawing and gesticulating enabled us to achieve an understanding that no words could have conveyed.
Bumi returned home with valuable experience, we at Chialab are very satisfied and BCBF should be proud.
We await her efforts, but I believe that whatever the outcome, the value lies in the process, in the method, in the visual gymnastics that the VIW put us through, which I am sure will have an effect far beyond the six illustrations that Bumi sends us for BCBF26.
Thank you
Beppe
With these words we ended the tenth edition of VIW in July 2025. Ten years have passed since Elena Pasoli asked us what we thought about using illustration to recount the 2017 edition of the Children’s Book Fair, an initiative that signified a break with a long iconoclastic tradition. I remember feeling a thrill very similar to the sensation of leaving a safe harbour to set sail on an unknown course. We obviously accepted the challenge but proposed two conditions: firstly, the youth of the participants, and secondly, workshops at Chialab. And this is how we have arrived at the tenth edition of VIW.
The story of the method and the protagonists of BCBF 2026
The preselection. April 2025.
Bumi Cha (2004), South Korea; Stefania Serafinescu (1996), Romania; Booali Tooba (1996), Iran; and Lee Hsuan Jung (1994), Taiwan, were chosen from the candidates for the 59th edition of the Illustrators Exhibition. The theme we proposed was ‘faces’, not necessarily human ones, viewed from the front, direct gazes that represent the immersion in, and identification with, the stories they read.
For us Bumi Cha’s proposals, her drawing and her way of seeing a portrait showed great promise. In her drawing the boundaries that define the shapes play dynamically between what is outside and what is within. This delicate ambiguity fascinated us and seemed to be the most suitable way to convey the diversity of the faces that attend BCBF.
BCBF VIW. Bologna, 15-18 July 2025
Bumi Cha arrived from South Korea and joined us on the morning of the 15th. The Chialab studio was all set to welcome her and put her in the best possible position to understand what the Bologna Children’s Book Fair is, its atmosphere, and its story that can be told through thousands of objects.
The theme for 2026 will be permeated by faces, features and portraits. From the forehead to the chin, A space in which to build a dense and intense relationship between gazes.
We were to work together on 6 visual exercises. Small practical workshops to better understand the theme and to culminate in designing a matrix. We try not to fall into the “labile fantasizing” that Italo Calvino spoke of, rather we aim to cultivate the imagination methodically, persevering to seek out the image-pattern best suited to BCBF 2026.
Exercise 1. All Kinds of Characters / Observe and group the portraits according to common criteria. Exercise 2. Pareidolia / Divide each portrait into 6 parts. Do not crop the feature you are interested in. You are free to divide the sheet as you prefer. Look at the 144 cut-outs and decide whether and how to group them. Exercise 3. Fiṡionomic machine / Construct 2 portraits each (one good and one bad) using 6 of the 144 parts cut out in exercise 2. Each portrait must contain six pieces of paper. Exercise 4. Who’s That Face? / Choose one of these jobs or places: florist, shoemaker, grocery store, bakery. Construct a portrait using only objects related to the jobs/places. Exercise 5. Selfie / Pose, take 3 photos: front, ¾ view and profile. Cut the selfie into 6 parts as in Exercise 1. Construct the portraits using parts of the three poses. Exercise 6. The Matrix / Construct a pattern by dividing the square into 6 parts. Draw 4 very different faces using the same matrix.

The matrix or generative pattern is the system that enables us to produce multiple, adaptable combinations of faces, each of which is recognisable as BCBF 26 and, at the same time, representative of the many unique differences. Finally, we must say goodbye, leaving Cha Bumi with a suitcase full of insights and ideas and just one task: to design 6 faces-portraits-characters that can be deconstructed, reproduced and multiplied.
The first is good. August 2025
Bumi sends her first ideas. We immediately understand that she is on the right track. Her approach, her design and her technique embrace and develop the inputs from VIW, resulting in a strong, dynamic, decisive, multifaceted and unique proposal. The image for BCBF 26 can be seen to be clearly taking shape.
The matrix
One of the aims of VIW, perhaps the most complex to explain and the hardest to achieve, is to ask not for a single image, but a generative system that makes it possible to produce multiple combinations from a small number of elements.
Taking part in VIW were Bumi Cha, Alex Weste, Michele Tomasini, Clara Rizzolino.
The workshops were coordinated by Beppe Chia and Jessica Cantoni.
